    • For RNA = ribose
  74. Describe the basic idea/process of DNA and RNA...
    • DNA is like the basic blueprint of a cell, RNA is messenger w/in the cell
    • Messages stored in bases of DNA must be transferred to ribosomes to make proteins
    • So through transcription, cells copy instructions in DNA into RNA and send the messenger RNA to the ribosomes
    • At the ribosomes, translation happens as proteins are made by from the instructions in RNA and sent out to entire cell
    • DNA, RNA< and ribosomes work hand in hand to produce the proteins necessary for life in cells
  75. Specific base pairing rule w DNA replication
    • A-T 
    • C-G
    • and vice versa: T-A, G-C
    • *REMEMBER: A always binds to the base that is different btwn RNA and DNA. Therefore, it will always bind w either a T or U. G and C stay together.

    • refines proteins made by ribosomes, sorts proteins and prepares them for transport to other part of cell or for secretion, works w ER in protein movement & processing
  82. Vesicles
    • small membrane-bounded sacs w/in cytoplasm used to transport proteins & other substances into and out of the cell
    • Many types, but most common:
    • Vacuole, lysosomes, and peroxisomes

    • have cristae (series of folds) inside in which enzymes are found
    • These enzymes help convert sugar into ATP to power the cell
  87. microtubules

    • -G1 (also called "growth-1" or "gap-1")
    • -S (replication of DNA)
    • -G2 (growth-2 or "gap-2")
  95. G1
    • happens after mitosis, 
    • takes 8 - 10 hours to complete
    • Cell duplicates organelles and cytoplasmic components
    • DNA double helix unwinds to expose the bases, RNA pairs w complementary partners on DNA to form messenger RNA
    • Once entire gene is copied into messenger RNA, mRNA exits nucleus and takes info to ribosome
  96. quiescent
    a resting state, cell is incapable of cell division, parked in cell cycle called G0
  97. G0
    • pronounced "Gee-zero"
    • If cell cannot pass the G1/S checkpoint, or is quiescent (not actively dividing) remains in G0
    • where cell exits cell cycle, gets "off merry-go-round"
    • *G0 Lock happens when a cell never comes out, or never divides again. Like neurons spend lifetime here
    • Other cells (like liver, kidney) may wait here for up to several years but can prepare for division if needed
  98. S
    • phase in interphase, stands for "synthesis" (for DNA)
    • replication of DNA so it can be divided equally btwn daughter cells  (went from 46 to 92 chromatids)
    • takes 8 hours
  99. Exactly how does DNA double helix can be released to allow replication
    • The double helix unwinds w help of enzymes
    • This breaks the hydrogen bonds btwn base pairs & separates the bases, but does not remove the bases from the backbone of their half of double helix
    • The exposed bases pair w new complementary bases that are synthesized into new strands w help of DNA polymerase
    • The two strands go through the same process at the same time
    • Thus, two new strands of identical DNA form; each has one strand of original and one strand that was newly synthesized
  100. G2
    • last part of interphase, finalizes it's preparations for mitosis
    • Includes continued protein synthesis and cell growth in preparation for cell division
    • Cell now carries double amount of normal DNA 
    • Duplication of centromeres, now has 92 DNA molecules
    • Second checkpoint must be crossed
    • takes 4 - 6 hours
  101. Mitosis
    • M phase ~ the actually, active process of cell division
    • takes about 30 minutes
    • 4 stages: prophase, metaphase, anaphase, telophase
    • "please meet aunt teresa"
  102. prophase
    • first phase of mitosis
    • DNA is tightly packed into chromosomes
    • nuclear envelope breaks down
    • mitotic spindle forms and centrioles move to opposite sides of cell
  103. metaphase
    • everything in parent cell lines up in middle (at metaphase plate)
    • chromosomes (formed in prophase) move to middle of parent cell and microtubules of mitotic spindle attach to anchors (centromeres)
  104. anaphase
    • the phase of mitosis where the contents of the two daughter cells move backwards, away from each other
    • chromatids are torn apart in two equal pieces
    • cytokinesis begins (which separates the 2 sets of chromosomes into different cells)
  105. telophase
    • mitosis is complete ("telo: end")
    • identical sets of chromosomes are at opposite ends of cell
    • spindle fibers disappear, nuclear membranes reappear, cytokinesis completes
    • cleavage furrow appears, cell split
  106. Mitosis vs. Cytokinesis
    • Mitosis: process of nuclear division. Genetic material must be parcelled equally btwn cells, chromosomes form, get pull apart, dissolve
    • Cytokinesis: process of cell division (happens at end of mitosis, in cytoplasm & organelles). plasma membrane of cells tightens like rubber band and pinches off two cells. Separates genetic material cytoplasm and organelles into two equal daughter cells.
  107. chromosome #'s
    • called "n"
    • Each daughter cell must have appropriate amount of DNA: two copies of each gene, called a diploid # (2n)
    • Cells which have only one copy of each chromosome are called haploid (sperm n egg)
  108. gametes
    • male gamete = sperm
    • female gamete = egg
    • the cells that form a new organism via sexual reproduction (w gametes from both sexes combine)
  109. chromatids
    • a single, continuous DNA strand w an unbroken backbone of deoxyribose-phosphate
    • two linked in the middle (by centromere) make up the chromosome
    • so, one chromatid makes one part of the "x" of a chromosome
  110. meiosis vs mitosis
    • Mitosis creates two daughter cells that are identical to the "parent"
    • Meiosis halves the DNA content in Meiosis I and then Meiosis II resembles mitosis
  111. homologous chromosome
    • Occurs in a diploid cell (which has 2 sets of chromosomes), in which each individual chromosome has a twin chromosome (homologous)
    • it is almost identical in size, function and genes
  112. Prophase I ~ Meiosis
    Homologous chromosomes condense and link in the process, forming tetrads. This allows crossing over or recombination to occur

    *Tetrads refer to the set of chromosomes next to each other, right before crossover takes place. There are technically 4 chromatids (tetra = 4)
  113. Metaphase I ~ meiosis
    • Homologous chromosomes search out it's homologous (basically, it's twin chromosome) and they both move to the metaphase plate (midline)
    • Therefore, there's 2 chromosomes lines up together, each consisting of 2 chromatids
  114. Anaphase I ~ Meiosis
    The homologous chromosomes (twins) separate BUT THE SISTER CHROMATIDS OF EACH CHROMOSOME STAY TOGETHER
  115. Telophase I ~ meiosis
    • cytokinesis has occurred
    • Two haploid daughter cells are the result

    *From here, the cell does not rest but continues into meiosis 2
  116. Prophase II ~ meiosis
    brief stage in which spindle fibers again begin to form and centrioles move to opposite poles
  117. metaphase II ~ meiosis
    Sister chromatids (chromosomes) align at new metaphase plate
  118. Anaphase II ~ meiosis
    Sister chromatids separate again
  119. Telophase II ~ meiosis
    Four haploid cells result after cytokinesis
  120. autotroph
    • refers to an organism that can produce it's own food
    • most use photosynthesis to live
  121. heterotrophs
    • organisms that cannot produce their own food
    • they use cellular respiration in order to produce ATP from glucose
  122. photosynthesis
    • the process carried out by gree plants, green algae, and certain, bacteria, in which the energy from sunlight is trapped by the green pigment chlorophyll and used for synthesis of glucose
    • They can do this because of the special organelle chloroplast, which is where the chemical changes happen
  123. cellular respiration
    • the process by which glucose is broken down by glycolysis, which transfers some of the energy in glucose to ATP
    • The end products of glycolysis are fed into citric acid cycle (Krebs cycle) to produce more ATP
    • Together, glycolysis and the citric acid cycle constitute cellular respiration
  124. euchromatin
    unspooled, open, ready chromatin
  125. codon
    • A code of hereditary info on a gene; made up of sequences of the nitrogenous bases of DNA.
    • Each piece of the code is referred to as a codon and is composed of 3 bases. 
    • There are 64 codons (since 64 different 3-letter combo's can be formed from A, T, C, and G)
    • Each one matches a specific amino acid
    • *since there are 20 different amino acids, some codons match to same amino acid. Recall chains of amino acids make proteins
  126. genome
    a complete set of DNA for an individual that contains all genes
  127. mutagen
    a substance the induces mutations
  128. How can a mutation in the genome occure
    • errors in DNA replication 
    • or via a mutagen
    • *Cells do have back-up plans in place for both, so it greatly reduces the overall rate at which mutations arise
  129. mismatch pair
    • a back-up plan cells have if DNA bases are mis-matched in cell replication
    • After new DNA is replicated, it is proof-read to find any mistakes. 
    • If a mismatch is found, it repairs it by removing the incorrect base and replacing it with a proper one
    • IF a mutation squeaks through the cracks of this system, the DNA sequence from then on is altered. Certain forms of cancer arise this way
  130. excision repair
    Recall that during a cells life, may be exposed to certain substances capable of damaging DNA, such as harmful chemicals to UV rays from the sun

    • This is a mechanism which inspects DNA for this type of damage and attempts to repair it. 
    • Since modifications by mutagens often occur over a section of DNA (opposed to individual bases), this repair system will cut the defective strand of DNA, remove those bases that are near (including mutated ones) and allow DNA polymerase to generate a new, correct piece of DNA
    • Certain skin diseases are a result from this excision repair mechanism not working right
  131. germ cells
    • the reproductive cells that give rise to sperm and ovum
    • *any DNA mutations an individual may develop over their lifetime that lead to certain diseases, disorders or cancer, the mutations will only be passed on if they are present in the DNA germ cells

    • PE = mgh; where
    • m= the mass of the object
    • g = the standard gravity constant
    • h = the height at which an object is located
  140. Law of Conservation of Energy
    • says that energy is not lost but rather transferred back and forth btwn KE and PE
    • Therefore, given a fixed amount of total energy in a system, an increase in KE will result in a decrease in PE (and vise versa), but the total energy will remain the same
    • *(Where KE = kinetic energy, PE = potential energy)

  145. Recall the masses of protons, electrons and neutrons
    • Protons and neutrons have approximately the same mass
    • an electron's mass is much less
    • Therefore, the total mass of an atom is driven primarily by it's number of protons and neutrons according to the mass number
  146. mass number
    the total # of protons and neutrons found within the nucleus of an atom
  147. atomic mass
    recall that a given atom can have several versions (called isotopes) that differ by the mass number

    • *always the number written on the bottom of the box in the periodic table
  148. How can you find the # of neutrons
    • Recall the # of neutrons + the # of protons = the mass number
    • So subtract your # of protons from the mass number
  149. isotope
    • atoms with the same # of protons, but different numbers of electrons
    • making the mass number vary for the same type of atom

    *recall, the mass # is protons & neutrons added together!!
  150. purpose of catalysts
    • they increase reaction rates by lowering activation energy (so similar to enzymes)
    • control the rate of chemical reactions, or reactions in which atoms react to come to a stable state
    • Generally not consumed during reactions; so can start over once a reaction is finished:
  151. Example of general reaction with catalyst
    • Is a four step process, where X and Y are reactants, C is catalyst, and Z is new product:
    • X + C → XC
    • XC + Y → XYC
