Question

multiple - choice question \what is the role of polymerase in dna replication?\ \it synthesizes enzymes needed for replication.\ \it introduces key players in the replication process.\ \it bonds nucleotides to form a new double helix.\ \it acts as a proofreader to check for mistakes in replication.\

Explanation:

DNA polymerase is an enzyme that adds nucleotides to the growing DNA strand during replication, bonding nucleotides together to form a new double - helix structure. It does not synthesize other enzymes for replication, introduce key players, or act mainly as a proofreader (though some polymerases have proof - reading activity). Its primary role is nucleotide addition for new strand synthesis.

Answer:

It bonds nucleotides to form a new double helix.
