During DNA replication, what does a cell copy?
A
Only the RNA sequence needed to build ribosomes
B
The amino acid sequence of all cellular proteins
C
Only the phospholipid bilayer components of the plasma membrane
D
The nucleotide sequence of its DNA to produce two identical DNA molecules

Understand that DNA replication is the process by which a cell makes an exact copy of its DNA before cell division.
Recognize that DNA is composed of a sequence of nucleotides, which are the building blocks of genetic information.
Recall that during replication, the cell copies the nucleotide sequence of its entire DNA molecule to ensure genetic information is preserved.
Note that RNA sequences, amino acid sequences, and phospholipid bilayers are not directly copied during DNA replication; instead, they are produced or synthesized through other cellular processes.
Conclude that the correct answer is that the cell copies the nucleotide sequence of its DNA to produce two identical DNA molecules.
