How are the bases paired in the dna molecule
WebEach base pair should consist of one pyrimidine and one purine, held together by hydrogen bonds. If paired correctly, each base pair will consist of three 'rings'. If two purines paired there would be four 'rings' and they wouldn't fit or would distort the structure of … WebIn molecular biology, a histone octamer is the eight-protein complex found at the center of a nucleosome core particle.It consists of two copies of each of the four core histone proteins (H2A, H2B, H3, and H4).The octamer assembles when a tetramer, containing two copies of H3 and two of H4, complexes with two H2A/H2B dimers.Each histone has both an N …
