Dna structure and base pairing
WebA DNA molecule consists of two strands. Each strand is made up of a string of tiny building blocks called nucleotides. There are four types of nucleotides in DNA, represented by the letters A, T, C, and G. The nucleotides in opposite strands are joined together through complementary base pairing: A pairs with T, and C pairs with G. WebDouble-stranded DNA has a regular geometric structure with a fixed distance between the two backbones. This requires the bases pairs to consists of one base with a two-ring …
