The replication bubble is created when the process of DNA replication is initiated by helicase enzymes unwinding DNA at the origin of replication. This process occurs during the S phase of the cell cycle. What initiates the replication bubble? The replication bubble is initiated by the unwinding ...
**DNA**(deoxyribonucleic acid)is the genetic material of all known life from the simplest one-celled bacteria to the most magnificent five-ton elephant on the African plain. "Genetic material" refers to the molecules that contain two important sets of instructions: one formaking proteinsfor the ...
Magnesium ions (and perhaps other cations) play an important role in maintaining the structure of the ribosome. Dissociation into subunits occurs when Mg2+is removed. The precise role (or roles) of Mg2+remains uncertain, although interaction with ionized phosphate of subunit RNA is presumed....
thereplicationof genetic material. Once the genetic material has been copied and there are sufficient molecules to support cell division, the cell divides to create two daughter cells. Through many such cycles of cell growth and division, each parent cell can give rise to millions of daughter ...
