Initiation genetics
Did you know?
Initiation factors are proteins that bind to the small subunit of the ribosome during the initiation of translation, a part of protein biosynthesis. Initiation factors can interact with repressors to slow down or prevent translation. They have the ability to interact with activators to help them start or increase the rate of translation. In bacteria, they are simply called IFs (i.e.., IF1, IF2, & IF3) and in eukaryotes they are known as eIFs (i.e.., WebbSummary The regulation of chromosome replication initiation was studied at various temperatures with an E. coli dnaA46 strain and its dnaA + parent.
