Guide to Genetically Important Base Pairs

Adenine Thymine - by Jypx3 Base pairs that are associated with chemical structures determining heredity are nitrogen-containing organic compounds chosen from among four simple structures in the case of DNA—adenine (A), cytosine (C), guanine (G), and thymine (T). Adenine pairs with thymine—(A/T) and guanine pairs with cytosine (G/C). Interestingly, in the case of RNA, uracil (U) replaces the base thymine. The bonding that unites the base pairs is of an energetically weak variety called “hydrogen bonding.” What can we learn of and by these base pairs? Find out by reading informative articles written by Bright Hub contributors.
