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 chain… WebDNA contains 2 anti-parallel strands of complementary bases: DNA is made up of polymers of nucleotides. DNA forms a double helix. Each complimentary strand runs antiparallel to its adjacent strand. Phopshate is at the 5 end always. The sense strand of DNA runs from the 5’ to 3’ whilst the antisense strand runs from 3’ to 5’.
