Card Set Information
calculated by multiplying the magnification of the eyepiece by the magnification of the objective lense
light microscope that has two lens systems: the objective and the eyepiece
Lens that stays in focus when magnification/focal length is changed.
the object in the center of view will remain in the center when the objective is rotated
adapting for or using both eyes
Depth of Field
the distance between the nearest and the furthest objects that give an image judged to be in focus in
Field of View
The extent of the visible image field that can be seen
distance between the front lens of the objective and the coverslip
Process by which molecules of a solvent pass through a semipermeable membrane, equalizing the concentrations on each side
process of passive transport which molecules diffuse across membranes with the help of transport proteins
the movement of ions across a cell membrane into a region of higher concentration assisted by enzymes which require energy
transport of a substance across a cell membrane by diffusion that does not require energy
the state of a solution in respect of osmotic pressure
lower osmotic pressure
having the same pressure
a compound of nucleosides linked to a phosphate group
the synthesis of DNA consists of 1/2 original DNA strand and 1/2 new DNA
When one strand of the DNA runs in the 5' to 3' direction and the opposite strands runs in the 3' to 5' direction
a sequence of three nucleotides that together form a unit of genetic code in a DNA or RNA molecule
A sequence of three adjacent nucleotides in transfer RNA that binds to a corresponding codon in messenger RNA and designates a specific amino acid during protein synthesis
having a single set of unpaired chromosomes
containing two complete sets of chromosomes, one from each parent.
A pair of chromosomes having the same gene sequences, each derived form one parent
when a single chromosome is replicated into two copies of itself
Long strands of DNA and proteins that contain hereditary information
the point on a chromosome by which it is attached to a spindle fiber during cell division.
another term for centromere
the exchange of genes between homologous chromosomes, resulting in a mixture of parental characteristics in offspring.
