WebMay 21, 2014 · In addition, the A-form helix is slightly unwound with 11–12 nucleotides for every 360° turn, while in B-DNA there are 10–10.5 nucleotides. The helix axis runs almost straight through the centre of the base pair in the B-form, while in the A-form the centre of the base pairs are shifted about 4.5 Å from the axis.

WebMar 15, 2024 · Base pairs occur when nitrogenous bases make hydrogen bonds with each other. Each base has a specific partner: guanine with cytosine, adenine with thymine (in DNA) or adenine with uracil (in RNA). The hydrogen bonds are weak, allowing DNA to ‘unzip’. This lets enzymes replicate the DNA. WebSep 2, 2024 · The genetic information is encoded in the DNA by the specific combination of nitrogenous bases. These are the four nitrogenous bases in DNA: Adenine (A) Thymine (T) Guanine (G) Cytosine (C) These above base pairs are present in the strands of DNA where they specifically bond with each other by hydrogen bonding and connect the two strands. bismuth subsalicylate for kids
