In prokaryotes, DNA replication initiates at a single defined origin and proceeds bidirectionally via a multiprotein replisome that unwinds the duplex and synthesises new strands. Elongation is ...
In prokaryotic cells, transcription (DNA to mRNA) and translation (mRNA to protein) are so closely linked that translation usually begins before transcription is complete. In eukaryotic cells, however ...
Why have bacteria never evolved complex multicellularity? A new hypothesis suggests that it could come down to how prokaryotic genomes respond to a small population size. Every organism visible to the ...
