8:3. DNA Libraries and Generating cDNA
Prot —> mRNA —> cDNA —> dsDNA. (Step 2 via reverse transcriptase and step 3 via DNA Polymerase). Now the dsDNA is injected into a virus which infects bacteria to make lots of the DNA.
-
8:2. Polymerase Chain Reaction
Denaturation (Heat to high temp), Primer Annealing (Cool slightly), Primer Extension via polymerase (Heat but not as much as step 1).
-
8:1. Gel Electrophoresis
GE find us the length of a DNA Strand (how many base pairs long).
-
7:5. Applying the HP Equation
Not really sure why I did a module on this - basically you know they’re homo recessive because they have blue eyes (the recessive trait), and you know to use q BECAUSE we’re dealing with the recessive trait.
-
7:4. The Hardy-Weinberg Equation
HP Equation gives P(allele frequencies). P^2 is probability of homo dominant, Q^2 is probability of homo recessive, 2pq is probability of heterozygous allele combo. P = frequency of dom allele, Q = frequency of recessive allele.
-
7:3. Worked Example: Punnett Squares
Discusses Dihybrid Crosses and the Law of Independent Assortment.
