Which of the following reactions DNA polymerases can catalyze?

Which of the following reactions DNA polymerases can catalyze?

DNA Replication. The formation of a phosphodiester bridge is catalyzed by DNA polymerases. DNA polymerases catalyze the formation of a phosphodiester bond efficiently only if the base on the incoming nucleoside triphosphate is complementary to the base on the template strand.

What is not a function of DNA polymerase?

DNA polymerase adds new nucleotide on the growing DNA strand, checks for errors occurred during replication, and repairs those errors. It does not have helicase activity, means it cannot unwind the double-stranded DNA helix. Thus, the correct answer is option (c).

Is DNA polymerase a catalyst?

DNA polymerase’s rapid catalysis is due to its processive nature. Processivity is a characteristic of enzymes that function on polymeric substrates. In the case of DNA polymerase, the degree of processivity refers to the average number of nucleotides added each time the enzyme binds a template.

What do DNA polymerase 1 and 3 do?

DNA polymerase 3 is essential for the replication of the leading and the lagging strands whereas DNA polymerase 1 is essential for removing of the RNA primers from the fragments and replacing it with the required nucleotides. These enzymes cannot replace each other as both have different functions to be performed.

What is the function of DNA polymerase III quizlet?

DNA polymerase III adds DNA nucleotides to the primer(s), synthesizing the DNA of both the leading and the lagging strands.

What does each enzyme do in DNA replication?

In Summary: Major Enzymes

Important Enzymes in DNA Replication
Enzyme	Function
DNA helicase	Unwinds the double helix at the replication fork
Primase	Provides the starting point for DNA polymerase to begin synthesis of the new strand
DNA polymerase	Synthesizes the new DNA strand; also proofreads and corrects some errors

What two enzymes are used in DNA replication?

1 Answer. DNA primase and DNA polymerase.
