While studying replication in a bacterial variety, you found high rate of mismatch errors in newly synthesized dna strand after each cycle of replication. Name the enzyme(s) and their activity that is/are affected in this new bacterial variety.

hala mate,
- DNA replication is semiconservative. Each strand in the double helix acts as a template for synthesis of a new, complementary strand.
- New DNA is made by enzymes called DNA polymerases, which require a template and a primer (starter) and synthesize DNA in the 5' to 3' direction.
- During DNA replication, one new strand (the leading strand) is made as a continuous piece. The other (the lagging strand) is made in small pieces.
- DNA replication requires other enzymes in addition to DNA polymerase, including DNA primase, DNA helicase, DNA ligase, and topoisomerase.
hope it helps!
