Which statement is true about DNA replication?

DNA replication involves unzipping sections of DNA and base pairing that assembles nucleotides into complementary strands that are used to build the proteins that move to the new cells during cell division.

DNA replication involves unzipping the DNA molecule, followed by base pairing, which adds complementary nucleotides, to form two new identical DNA molecules that move to the new cells during cell division

DNA replication involves base pairing to build two new complementary strands, followed by unzipping into two new identical DNA molecules that move to the new cells during cell division.

DNA replication involves unzipping the DNA molecule into two identical strands which then move to the new cells during cell division.

The second option is the right one.

For DNA replication to occur, an existing double-stranded DNA (dsDNA) must be "unzipped" to form two strands of single-stranded DNA (ssDNA). The ssDNA then serves as the scaffold onto which a complementary strand of DNA is built by adding nucleotides one by one. At the end of this process, there are two identical strands of dsDNA, which then move into the daughter cells.
