Thus, viral ATP-dependent DNA ligases have an intrinsic nick-sensing function. Nick recognition by vaccinia DNA ligase and Chlorella virus DNA ligase also depends on occupancy of the AMP binding ...

bacterial DNA) recognition and signaling. Perhaps the most interesting aspect of CpG DNA recognition by a TLR is its evolutionary implications. Recognition by TLRs and innate immune recognition in ...

Scientists who have described in a new study the step-by-step details of a bacterial defense strategy see the mechanism as a promising platform for development of a new genome-editing method.

Sierra Bouzigard was 19 years old when she was murdered and left beaten beyond recognition by the side ... bits of skin containing her killer’s DNA underneath her fingernails.

COVERT TOWNSHIP, Mich. — Nearly 50 years later, a body found burned beyond recognition finally has a name. Advanced DNA testing has given investigators a break in a Van Buren County cold case ...

He predicted that the restriction enzyme and the modification enzyme act on the same DNA sequence, called a recognition sequence. In this way, the bacterial cell's own self-defense mechanism ...

Scientists used the restriction enzymes to, among other things, cut DNA at particular locations and insert new genes at the cutting sites. However, it is difficult to determine in advance exactly ...
