Which enzyme catalyzes the elongation of a DNA strand in the 5 to 3 direction quizlet?
DNA polymerase is the enzyme that catalyzes the addition of a nucleotide onto the 3′ end of a growing DNA strand. A hydroxyl is present at the 3′ end of the growing DNA strand. What is at the 5′ end? You just studied 42 terms!

Which DNA polymerase has 5 to 3 polymerase activity?
DNA polymerases
Which one of the polymerase have 5 to 3 exonuclease activity?
DNA Polymerase I
Which of the following enzymes has 5 to 3 exonuclease activity?
DNA polymerase I
What is 5 ‘- 3 exonuclease activity?
The 5′-3′ exonuclease activity is the only active component of the N-terminus fragment of DNA Polymerase I. The main duty of the 5′-3′ exonuclease activity is to remove the RNA primers at the 5′ ends of newly synthesized DNA so that the polymerase activity can fill in the resulting gaps.
Which of the following polymerases has 5 → 3 exonuclease activity in E coli?
II. Telomerase has a 5′ 3′ polymerase activity.
Which of the following has 3 to 5 polymerase activity?
DNA polymerase III (polIII) holoenzyme of Escherichia coli has 3′—-5′ exonuclease (editing) activity in addition to its polymerase activity, a property shared by other prokaryotic DNA polymerases. The polymerization activity is carried by the large alpha subunit, the product of the dnaE gene.
Which DNA polymerase has 5 to 3 exonuclease activity?
DNA Polymerase I
Does DNA Polymerase I show 5 3 exonuclease activity 3 5 exonuclease activity or both?
II. Telomerase has a 5′ 3′ polymerase activity.
What is 5 ‘- 3 polymerase activity?
DNA polymerases III and I both have 3′ to 5′ exonuclease activity. This allows them to remove a mismatched nucleotide that has just been added to a growing DNA chain and make another attempt to insert the correct nucleotide.
Can DNA polymerase synthesize from 3 to 5?
DNA Polymerase Only Moves in One Direction After a primer is synthesized on a strand of DNA and the DNA strands unwind, synthesis and elongation can proceed in only one direction. As previously mentioned, DNA polymerase can only add to the 3′ end, so the 5′ end of the primer remains unaltered.
How do DNA polymerases synthesize DNA in the 5 to 3 direction?
Since DNA polymerase requires a free 3′ OH group for initiation of synthesis, it can synthesize in only one direction by extending the 3′ end of the preexisting nucleotide chain. Hence, DNA polymerase moves along the template strand in a 3’5′ direction, and the daughter strand is formed in a 5’3′ direction.
What direction does DNA polymerase 3 synthesize in?
This constraint is due to the antiparallel nature of DNA and the ability of DNA polymerases to synthesize DNA only in the 5u2032 3u2032 direction. As the replication fork progresses, new primers are synthesized by primase on the lagging strand.
