DNA replication creates 4 new molecules of DNA.

The molecules produced by replication are identical.

DNA replication occurs during Interphase of the cell cycle.

Each of the DNA molecules produced contains one original strand and one new strand.

Genes are segments of DNA.

Genes code for making proteins.

Genes control our inherited traits.

Each chromosome has only one gene on it.

DNA is found in the nucleus of the cell for eukaryotic organisms.
