How many copies of a DNA molecule result from two replications of a single DNA molecule?
A
8 copies
B
6 copies
C
4 copies
D
2 copies
Verified step by step guidance1
Understand that DNA replication is a process where a single DNA molecule is copied to produce two identical DNA molecules.
In the first replication, one DNA molecule is duplicated to form two identical DNA molecules.
In the second replication, each of the two DNA molecules from the first replication is duplicated again.
Calculate the total number of DNA molecules after the second replication: 2 (from the first replication) x 2 (each replicates again) = 4.
Conclude that after two rounds of replication, there are 4 copies of the original DNA molecule.
