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. WebSpecific base pairing in DNA is the key to copying the DNA: if you know the sequence of one strand, you can use base pairing rules to build the other strand. Bases form pairs (base …
WebAug 30, 2024 · How are bases connected to the backbone of DNA? The two strands of DNA are actually connected by hydrogen bonds (H-bonds) between the nitrogenous bases. There are 2 hydrogen bonds between adenine and thymine, and 3 hydrogen bonds between cytosine and guanine. What is the bond between the nitrogenous bases called? WebJan 14, 2024 · Double-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 …
WebTo make a DNA molecule you need: nitrogenous bases—there are four of these: adenine (A), thymine (T), cytosine (C), guanine (G) carbon sugar molecules phosphate molecules If you take one of the four nitrogenous bases and put it together with a sugar molecule and a phosphate molecule, you get a nucleotide base. WebNucleic acids, macromolecules made out of units called nucleotides, come in two naturally occurring varieties: deoxyribonucleic acid ( DNA) and ribonucleic acid ( RNA ).
