The amount of energy that reactants in a chemical reaction must absorb before the reaction can start.
A protein that serves to enchance the transcription of a gene.
Substrate-binding region of an enzyme.
The ATP-requiring movement of substances across a membrane against their concentration gradient.
Trait that is favored by natural selection and increases an individual's fitness in a particular environment.
Diversification of one or few species into large and very diverse groups of descendant species.
Nitrogenous base in DNA, a purine.
Adenosine diphosphate (ADP)
A nucleotide composed of adenine, a sugar, and two phosphate groups. Produced by the hydrolysis of the terminal phosphate bond of ATP.
Adenosine triphosphate (ATP)
A nucleotide composed of adenine, the sugar ribose, and three phosphate groups that can be hydrolyzed to release energy. Form of energy that cells can use.
An organism, environment, or cellular process that requires oxygen.
Cellular respiration that uses oxygen as the electron acceptor.
A jelly-like slab used to separate molecules on the basis of molecular weight.
The percentage of the gene copies in a population that are of a particular form, or allele.
Geographic separation of a population of organisms from others of the same species. Usually in reference to speciation.
Factor other than the tested hypothesis that may explain observations.
abnormal cessaton of menstrual cycle.
Monomer subunit of a protein. Contains an amino, a carboxyl, and a unique side group.
An organism, environment, or cellular process that does not require oxygen.
A process of energy generation that uses molecules other than oxygen as electron acceptors.
Stage of mitosis during which microtubules contract and separate sister chromatids.
Phenomenon that holds normal cells in place. Cancer cells can lose anchorage dependence and migrate into other tissues or metastasize.
Information based on one person's personal experience.
Formation of new blood vessels.
Plant in the phyla Angiospermae, which produce seeds borne within fruit.
An organism that obtains energy and carbon by ingesting other organisms and is typically motile for at least part of their life cycle.
Kingdom of Eukarya containing organisms that ingest others and are typically motile for part of their life cycle.
Plant that completes its life cycle in a single growing season.
Annual growth rate
Proportional change in population size over a single year. Growth rate is a function of the birth rate minus the death rate of the population.
A chemical that kills or disables bacteria.
Characteristic of certain bacteria; a physiological characteristic that permits them to survive in the presence of particular antibiotics.
Region of tRNA that binds to mRNA codon.
Certain vitamins and other substances that protect the body from damaging effects of free radicals.
Feature of DNA double helix in which nucleotides face "up" on one side of helix and "down" on the other.
A transport protein in the membrane of a plant or animal cell that facilitates the diffusion of water across the membrane (osmosis).
Of, or relating to, water.
Domain of prokaryotic organisms made up of species known from extreme environments.
Selective breeding of domesticated animals and plants to increase the frequency of desirable traits.
A type reproduction in which one parent gives rise to genetically identical offspring.
Tendency for individuals to mate with someone who like themselves.
The smallest unit of matter that retains the properties of an element.
The number of protons in the nucleus of an atom. Unique to each element, this number is designated by a subscript to the left of the symbol for the element.
Enzyme found in the mitochondrial membrane that helps synthesize ATP.
Non-sex chromosome, of which there are 22 pairs in humans.
