Describe the double helix structure of DNA.
The double helix structure of DNA is composed (made up of) of three strands instead of two.
The double helix structure of DNA consists of two strands twisted around each other, made up of nucleotides with adenine pairing with thymine and guanine pairing with cytosine.
In the double helix structure of DNA, adenine pairs with guanine and thymine pairs with cytosine.
The double helix structure of DNA is a single-stranded linear molecule.
