Cascade, a complex of 11 proteins and a guide RNA, uses the sequence of the guide RNA to detect invading DNA. See pages 1452, 1473, and 1479 for a close-up look at Cascade before and after it binds to its target DNA.Illustration: Valerie Altounian/Science; protein coordinate data supplied by Scott Bailey 4 w7 t, W5 R" z# d4 c5 A3 }; c& }, Q* }/ F) g3 J 作者: 20084720113 时间: 2014-9-24 20:27
