Question

question 5 of 10
during dna replication, how is the leading strand built?
a. continuously, as nucleotides are added to the 3 end
b. continuously, as nucleotides are added to both ends
c. in short segments, as nucleotides are added to the 5 end
d. in short segments, as groups of nucleotides are added all at once

Explanation:

During DNA replication, DNA polymerase synthesizes DNA in the 5' - 3' direction. The leading - strand synthesis occurs continuously in the 5' - 3' direction as nucleotides are added one by one to the 3' end of the growing strand.

Answer:

A. Continuously, as nucleotides are added to the 3’ end
