Question 1
Transposons can integrate into the promoters of genes, what is the most likely outcome of such an event?
◦ frame shift
◦ altered gene expression
◦ amino acid substitution
◦ point mutation
◦ deamination
Question 2

E. coli with a mutation in the
phr gene?
◦ decrease in UV-induced mutations
◦ increase in UV-induced mutations
◦ decrease in reversion of base-pair substitution mutations
◦ increase in the methylation of nucleotide bases
◦ decrease in the methylation of nucleotide bases
