Question

Diea dna gyrase repair mistakes during dna replication

Answer 1

Answer:

Explanation:

DNA polymerases can only add nucleotides to the 3' end of an existing DNA strand. (They use the free -OH group found at the 3' end as a "hook," adding a nucleotide to this group in the polymerization reaction.) ... The primer primes DNA synthesis, i.e., gets it started.

Answer 2

Explanation:

In molecular biology, DNA replication is the biological process of producing two identical replicas of DNA from one original DNAmolecule. DNA replication occurs in all living organisms acting as the basis for biological inheritance. The cell possesses the distinctive property of division, which makes replication of DNA essential.
