C

D

Verified step by step guidance1
Understand that DNA elongation rate refers to how quickly DNA polymerase adds nucleotides to a growing DNA strand during replication.
Recall that prokaryotic DNA polymerases generally work faster than eukaryotic DNA polymerases due to differences in cellular complexity and replication machinery.
Consider the structural differences: prokaryotes have a simpler replication system with fewer proteins involved, which allows for a faster elongation rate.
Compare the typical elongation rates: prokaryotic DNA polymerase can add nucleotides at a rate of about 1000 nucleotides per second, whereas eukaryotic DNA polymerase adds at about 100 nucleotides per second.
Conclude that the rate of elongation of a DNA strand in prokaryotes is faster than the rate in eukaryotes based on these comparative rates.
