WebThe DNA double helix is composed of two strands of DNA; each strand is a polymer of DNA nucleotides. Each nucleotide consists of a sugar, a phosphate group, and one of four nitrogenous bases. The structure … WebApr 24, 2010 · To do this, it first has to unzip the nitrogenous bases. All the pairs of "AT" and "GC" are separated. The DNA then has two single strands. At this point new pairs are made, along with a new phosphate backbone, to create two new copies of DNA. Each single strand then pairs with a correct complementary base to create a new double-stranded …
