5. DNA repair enzymes preferentially repair mismatched bases on the newly synthesized DNA strand, using the old DNA strand as a template. If mismatches were instead repaired without regard for which strand served as template, would mismatch repair reduce replication errors? Would such a mismatch repair system result in fewer mutations, more mutations, or the same number of mutations as there would have been without any repair at all? Explain your answers.

The template strand of a transcribed gene is preferentially repaired because: a. it allows DNA replication folks move faster. b.the altered secondary structure of the RNA it produces is likely to be recognized by repair enzymes. c.it contains specific sequences for binding repair enzymes. d.damage on the nontemplate strand is less likely to result in mutation.

1. In prokaryotes, in the DNA repair mechanism called mismatch repair, A) enzymes that perform the repair can distinguish the new strand of DNA from the template strand because the template strand is methylated. B) if a mismatch is detected, the 2 bonds that the mismatched nucleotide forms with adjacent nucleotides are cleaved and that single nucleotide is removed and replaced by the correct nucleotide. C)each new nucleotide is "proofread" by DNA polymerase. D) A and B E) all of...
