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 ...

The Escherichia colihelicase, YoaA, and DNA polymerase III subunit, χ, form a complex (YoaA-χ) that promotes tolerance to the DNA chain-terminator 3ˈ-azidothymidine (AZT). Single-stranded DNA binding ...

E. coli divides faster than it can replicate its genome, while simultaneously expressing its genes. Scientists recently revealed the intricate molecular coordination that makes this possible. “It’s as ...

In biology you must have come across the two types of cells, the prokaryotic and eukaryotic cells. These two are the most fundamental forms of life on earth. Everything living from the bacteria on ...
