In a dna molecule which bases pair together
WebAug 3, 2024 · The rescue of stalled DNA replication forks is essential for cell viability. Impeded but still intact forks can be rescued by atypical DNA helicases in a reaction known as fork regression. This reaction has been studied at the single-molecule level using the Escherichia coli DNA helicase RecG and, separately, using the eukaryotic SMARCAL1 … WebIn DNA, these bases are cytosine (C), thymine (T), adenine (A) and guanine (G). Note: These are called "bases" because that is exactly what they are in chemical terms. They have lone pairs on nitrogens and so can act as electron pair donors (or accept hydrogen ions, if you prefer the simpler definition).
