DNA replication – Genes – the units of inheritance (6/10)

A double strand of DNA unwinds
and the strands separate. For each unwound strand,
the bases can now match with those
that are floating free in the cell. The familiar
base pairing rules apply. A pairs with T, G with C, and so on. So each strand of the double helix acts as a template for the formation
of a new complementary strand. This eventually gives
two DNA double helices, each identical to the original and actually containing
one old strand and one new.
