What are two functions of DNA polymerases during DNA replication?

Answer 1

DNA Polymerase has 2 main functions. The first is replication, or creating the new DNA strand from the template it has been given. The second is proofreading the new strand after it has been created to make sure it had been copied correctly.

Answer 2

matching complementary bases on nucleotides during DNA replication

introducing mutations into DNA for evolutionary adaptation

Some DNA polymerases proof read and correct errors, thereby reducing mutations and conserving the genetic code. Introducing genetic mutations is not a function of DNA polymerase, but obviously DNA polymerases are not perfect at detecting and correcting replication errors.

Answer 3

Continuously replicating the 5' to 3' [leading] strand while dis-continuously replicating the 3' to 5' [lagging] strand in short 5' to 3' Okazaki Fragments.

DNA unwinding, splicings and rewinding are 'separate' functions.

Some DNA polymerases proof read and correct base errors to reduce mutations and conserve the genetic code.

Answer 4

It adds nucleotides to the DNA and "proofreads" the created portion of DNA. Additionally, it removes the RNA primer from the DNA.

Answer 5

DNA polymerase is the primary enzyme responsible for DNA replication. Two of its major roles are: the polymerization of dNTP's or deoxyribonucleotides, and to proofread the new copies.

Answer 6

A. It joins individual nucleotides to produce a DNA molecule, which is a polymer.

B. It "proofreads" each new DNA strand.

Answer 7

DNA Pol III adds nucleotides to the 3' end of the new strand.

DNA Pol I removes RNA primers.

Answer 8

"It adds nucleotides to the DNA and "proofreads" the created portion of DNA. Additionally, it removes the RNA primer from the DNA."
