I’m having trouble with this questions can you explain this?

Transcribed Image Text:**Statement:**
"Release factors (RFs) that operate in translational termination are specialized tRNA molecules, with anticodons that specifically base pair with STOP codons."
**Question:**
True or false?
**Explanation:**
In the context of molecular biology, release factors (RFs) play a crucial role in terminating translation. They are not tRNA molecules but proteins that recognize the stop codon during translation and facilitate the release of the newly synthesized polypeptide chain from the ribosome. Unlike tRNA, which pairs with codons through anticodons, release factors do not contain anticodons but directly interact with the ribosomal machinery to end translation.
