Shape of a strand of dna
Webb29 juli 2024 · DNA is most often found in the classic double helix shape. This is made up of two strands running in opposite directions. Each strand will have nucleotide bases sticking out of it — those famous letters of A, T, C, and G. The bases from each strand match up in the middle to link together, with A pairing with T and C pairing with G.
