Shape of a strand of dna
Did you know?
DNA is a long polymer made from repeating units called nucleotides. The structure of DNA is dynamic along its length, being capable of coiling into tight loops and other shapes. In all species it is composed of two helical chains, bound to each other by hydrogen bonds. Both chains are coiled around the same axis, and have the same pitch of 34 ångströms (3.4 nm). The pair of chains have … Webb8 jan. 2024 · DNA Structure A single DNA molecule is shaped as a double helix made up of two strands of nucleotides that are bonded together. Each nucleotide consists of a nitrogen base, a sugar (ribose), and a phosphate group. The same 4 nitrogen bases are used as the genetic code for every strand of DNA, no matter which organism it comes …
