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.
WebbEven though the shape of DNA is often described as a ladder, it is not a straight ladder. It is twisted to the right, making the shape of the DNA molecule a right-handed double helix. This shape allows for a large …
