RNA strand that nearly self-replicates could unlock life’s origin
A 45-nucleotide strand of RNA can now synthesize both its mirror-image complement and a copy of itself, bringing scientists closer than ever to demonstrating how life could have emerged from chemistry ...
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 ...
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 ...
