An essential stage in cell division and reproduction, allowing genetic material to be copied into a new cell.

An essential stage in cell division and reproduction, allowing genetic material to be copied into a new cell. The four nucleotides in DNA – adenine, thymine, cytosine, and guanine – are arranged in complementary pairs in the DNA double helix. The DNA strand can unravel, and each strand's complementary nucleotide sequence is then recreated to produce an exact copy for the new cell.
