Question

Why is the new DNA strand complementary to the 3' to 5' strands assembled in short segments? Why is the new DNA strand complementary to the 3' to 5' strands assembled in short segments?

a.DNA polymerase can assemble
b.DNA only in the 3' to 5' direction
c.DNA polymerase can assemble
d.DNA only in the 5' to 3' direction

Answer 1

b.DNA only in the 3' to 5' direction

Step-by-step explanation:

Since that DNA can only be copied in the 3' to 5' direction, there will be a lagging strand which have to be assembled in short terms called Okazaki fragments, in human a the DNA polymerase is responsible for making the complementary nucleotides, and the DNA ligase enzyme is responsible to link the Okazaki fragments to the lagging strand.
