3 2 If there are no mutations during this process, which of the following pairs of strands will have identical base sequences? 1 and 2 1 and 4 2 and 4 O 3 and 4

Using the numbered sites on the DNA double helix strands below, where would the DNA Primer ACTTGCGA bind to for DNA Amplification?

5' 3' ORF for gene X +1 You find a mutation elsewhere in the genome (not within the sequence above) that you decide to call Mutation #2. When Mutation #1 in gene X (from the above question) is combined with Mutation #2 in the same organism, you get the phenotype in the blots below. This second mutation is most likely in what specific factor? Wild Type Northern Gene X O ribosome O sigma factor O DNA polymerase RNA polymerase Double mutant Wild Type Western Gene X direction of transcription Double mutant 3' 5'

The function of the 3'-> 5' exonuclease activity is found in which of the following: DNA Polymerase III DNA Polymerase I DNA Polymerase II All of the above
