In two related studies, researchers describe huge chromosomal rearrangements and about 500 novel gene clusters in the octopus, squid, and cuttlefish genomes, which they say could help explain how they evolved their extraordinary brains.
The relatively new technique for visually detecting chromosomal variants associated with disease risk performs at least as well as more established techniques in two recent studies.
Recruiting an epigenetic instigator of centromere formation into large segments of cloned DNA facilitates their transformation into artificial chromosomes.
