The rules of base pairing (or nucleotide pairing) are: A with T: the purine adenine (A) always pairs with the pyrimidine thymine (T) C with G: the pyrimidine cytosine (C) always pairs with the purine guanine (G) This is consistent with there not being enough space (20 Å) for two purines to fit within the helix and ... WebNov 6, 2008 · Two UCSD biologists announced the discovery of a human protein last week that rewinds single-stranded DNA into its normal double-stranded form, potentially preventing critical genes — such as those responsible for genetic disorders — from forming.
