Question 1

A dominant allele K is necessary for normal hearing. A dominant allele M on a different locus results in deafness no matter which other alleles are present. If a kkMm individual is crossed with a Kkmm individual, what percent of the offspring are deaf. Assume the genes are unlinked.

Answer 1

75%

Question 2

How many grams of NcCl is needed to make 1L of a 2MNaCL solution?

Answer 2

g=MW x MOL
mol= LxM 1x2 =2mol
g=58mw x 2mol= 116g

Question 3

DNA Replication

Answer 3

Toperisomerase unwinds, helices unzips, SS binding proteins hold open, DNA primes dna so bases can be added, RNA primers primes the RNA ad dna build on the lagging and leading strands

Question 4

How to read and make DNA

Answer 4

read 3’ to 5’
make 5’ to 3’

Question 5

How to read and make mRNA

Answer 5

read 5’ to 3’
make 3’ to 5’

Question 6

What are the three steps in PCR

Answer 6

1 denature DNA by heat
2 Anneal primers
3 Extend DNA using Tag polymerase which does not denature in high temps

Question 7

Why PCR?

Answer 7

Amplify DNA sections

Question 8
