Scientists look at the base pairs that compose the "rungs" of the DNA ladder to determine a genome's sequence. The success of E. coli bacteria depends on their ability to multiply very rapidly by ...
A series of electron micrographs show the barrel-shaped helicase with several components of the replisome: a) helicase (grey) with Ctf4 (light blue), which is a recruitment factor for the ...
DNA replication is essential to all life, yet many basic mechanisms in that process remain unknown to scientists. The structure of the replisome--a block of proteins responsible for unwinding the DNA ...
