Messenger RNA is produced via the process of transcription. DNA is transcribed into mRNA using RNA polymerase. First, the double helix structure of the DNA unravels, and the hydrogen bonds break between t...

Competitive inhibitors have a similar shape to the substrate and they compete with the substrate to bind to the enzymes active site. When they bind to the active site, they block the substrate from bindin...

• Both dominant and recessive allele frequencies will remain constant assuming the absence of migration, mutation and selection• p² + 2pq + q² = 1• Where p=frequency of A/N; p=freque...

• Hydrogen bonds holding base pairs in the anti- parallel strands are broken by an enzyme; the two halves of the molecule separate • DNA unwinds and the strands separate; DNA polymerase catalyses the addi...
