DNA nanotechnology works by taking advantage of the natural base pairing rules of DNA—adenine pairs with thymine and cytosine pairs with guanine—to design and synthesize specific sequences of DNA that ...

In all these cases, the base pairing in the genetic material takes place according to the rules that James Watson and Francis Crick first proposed.

In RNA, the same base-pairing rules apply, with the exception that uracil replaces thymine. Thus, in RNA, adenine pairs with uracil (A-U), and guanine pairs with cytosine (G-C). RNA plays a crucial ...
