Q13. A new DNA strand elongates only in 5'- 3' direction because
DNA polymerase can add nucleotides only to the 3' free end. The free OH group at 3' end acts as a hook to which nucleotide is added during polymerization.
As u see the other options, they are incorrect.
A. DNA polymerase never adds nucleotides to 5' end
B. It is not correct. actually new nucleotide is added at the 3' end only
C. Replication fork is formed irrespective of the fact.
hence option D is correct

Question 1 (0.5 points) Why is there a lagging strand and a leading strand during replication? O Because the helicase unwinds the dna in only one direction. Because DNA polymerase can only add nucleotides to the 3'end of a chain of nucleotides and replication proceeds in both directions. b) c) Because a primer must be laid down first. because DNA polymerase lacks proofreading ability.

When a dideoxynucleotide is incorporated into one new strand by DNA polymerase, 1.addition of nucleotides to all new strands stop. 2.addition of nucleotides only to that strand ceases. 3.nothing changes. 4.addition of nucleotides only to that strand speeds up. 5.nucleotides are removed only from that strand and then new nucleotides are added.

Which of the following statements about DNA replication is FALSE? Primase synthesizes the primers. DNA polymerase is required to add new nucleotides to the growing ends of the DNA strands. DNA ligase joins the small DNA fragments of the lagging strand. Only one strand of the parent DNA serves as a template for a newly synthesized complementary strand.
