Bacterial plasmids are circular or linear double-stranded DNA molecules defined by their capability of autonomous replication in the hosts. They are critical sources for microbial evolution and genome ...

Any DNA stretch that is about to replicate needs to unwind first, but how this happens — particularly the sequences that direct the process — is a bit of a mystery. New work has found that recruiting ...

A specific fraction of chromosomal DNA from both yeast and a wide variety of other eukaryotes, but not from Escherichia coli, promotes high-frequency transformation in yeast. The plasmids containing ...
