Question

As the two parental (template) DNA strands separate at a replication fork, each of the strands is separately copied by a DNA polymerase III (orange), producing two new daughter strands (light blue), each complementary to its respective parental strand. Because the two parental strands are antiparallel, the two new strands (the leading and lagging strands) cannot be synthesized in the same way. Drag each phrase to the appropriate bin depending on whether it describes the synthesis of the leading strand, the synthesis of the lagging strand, or the synthesis of both strands.

a. multiple primers needed
b. daughter strand elongates toward replication fork
c. only one primer needed
d. synthesized 5' to 3'
e. daughter strand elongates away from replication fork
f. made continuously
g. made in segments

Answer 1

a. multiple primers needed lagging strand

b. daughter strand elongates toward replication fork leading strand

c. only one primer needed leading strand

d. synthesized 5' to 3' both strands

e. daughter strand elongates away from replication fork lagging strand

f. made continuously leading strand

g. made in segments lagging strand

Step-by-step explanation:

a, g and e: the lagging strand is synthesized in segments.

b, c, f: the synthesis is continue.

d. DNA polimerase acts only in 5' to 3' sense.
