Question

During DNA replication, the 1. ______ strand is synthesized in the 5′ to 3′ direction. The strand that runs away from the replication fork is synthesized in 2.______ because. 3. ________________________
1.a)Okazaki
b)leading
c)lagging

2.a)in fragments
b)continuously
c)without primers
d)by RNA polymerase

3.a)DNA polymerase cannot synthesize in the 3' to 5' direction
b)RNA polymerase can only add primers to the leading strand
c)DNA polymerase cannot synthesize in the 5' to 3' direction
d)RNA polymerase can only add primers to the lagging strand

Answer 1

1: B. the strand that is assembled all at once is the leading strand and...
2. A the lagging strand is assembled in fragments because...
3. A it can only be synthesized 5' to 3'. it creates primers that let it build fragments I'm the 5' to 3' direction, which are later assembled to form a strand of DNA
