DNA Extraction Post-Lab Quiz

gel electrophoresis

technique that separates DNA fragments by size

agarose

seaweed product used to create gel matrix

wells

pits/depressions that PCR products are placed in

lanes

the area of gel that the PCR products traverse

bands

linear deposits of DNA visible after staining

longer

the heavier the band, the ___ it is

tier

the wells and lands of ½ of a 2-tiered agarose gel

ladder

DNA standard to give size reference

loading dye

adds color and viscosity to sample

DNA stain

uses electric charge to bind DNA

random mating, large population, and no mutation, migration, or natural selection

conditions for Hardy-Weinberg equilibrium to occur

Hardy-Weinberg equation

p² + 2pq + q² = 1

p + q = 1

p = positive allele freq. q = negative allele freq.
