Questions & Step-by-Step Solutions
What is the role of release factors in translation?
Step 1: Understand that translation is the process where proteins are made from RNA.
Step 2: Know that during translation, the ribosome reads the RNA in sets of three bases called codons.
Step 3: Recognize that some codons are special and signal the end of the protein-making process; these are called stop codons.
Step 4: Learn that release factors are special proteins that come into play when a stop codon is reached.
Step 5: Understand that release factors bind to the stop codon in the ribosome.
Step 6: Know that when the release factors bind, they trigger the release of the newly made protein from the ribosome.
Step 7: Finally, realize that this process effectively ends translation, allowing the ribosome to disassemble and be ready for the next round of protein synthesis.
