THIS IS JUST A START!!! There is much more, look over all of your notes! 1. Name the following mutations and explain how they can be suppressed (not fixed): A) In the mRNA, a premature stop codon arises. B) In the DNA, a mutation leads to the wrong amino acid inserted into the protein so it doesn’t fold properly. C) In the DNA, 2 additional nucleotides are inserted causing the proteins the sequence codes for to be truncated during translation. 2. The following DNA molecule: 5’-GATTAGCCTAGCCCCGGCGTAGCGTCAATTAATAT-3’ 3’-CTAATCGGATCGGGGCCGCATCGCAGTTAATTATA-5’ is incubated with the following primer: 5’-TATTAATT-3’ plus: dATP, dCTP, dGTP, and ddTTP; the DNA is denatured and a DNA pol is added. A) What is the length of the newly synthesized strand in bases?
