The double helix is a description of the molecular shape ... Two types of base pairing occur: nucleotide A pairs with T, and nucleotide C pairs with G.

DNA is a linear molecule composed of four types of smaller chemical molecules called nucleotide bases ... the molecular shape of DNA as a "double helix." Double-stranded DNA is composed of ...

The double helix unwinds, and each strand serves as a template for the synthesis of a new ... The genetic code is nearly universal across all living organisms, with only minor variations in some ...

Chances are you've seen an illustration of DNA's double-helix structure and even pictures of the chromosomes that comprise the human genome. But where and how does the famous double helix fit into ...

The backbone of the DNA double helix consists of alternating phosphate ... This is known as the base-pairing rule. A nucleotide consists of 1 phosphate, 1 sugar and 1 base. Each individual's ...

The DNA molecule was composed of the traditional sugar backbones and nucleotide pairs, but rather than the well-known right-handed spiral of the double helix structure, famously discovered by Watson ...
