How does the cell protect these strands from damage? How would you identify the protein that serves as a connector between DNA helicase and pol-a/primase? A simple yet often effective approach is ...

A DNA helicase, powered by ATP hydrolysis, propels itself rapidly along one of the template DNA strands (here the lagging strand), forcing open the DNA helix ahead of the replication fork.

Cells express their genes by converting the genetic message into protein. This process of protein synthesis occurs in two stages - transcription and translation. When a gene is to be expressed ...
