Question

1. ________ _____ degrades mRNAs that contain no stop codons.
2. _________________ _____ degrades mRNAs that contain premature stops.
3. In bacteria, a unique RNA that binds the A site of the ribosome and directs the addition of approximately 12 amino acids to the nascent peptide when no stop codon is present is called the __________________________.

Answer 1

Non-Stop Decay (NSD) Non-stop decay (NSD) is a cellular pathway that distinguishes and degrades abnormal mRNA transcripts that don't contain a proper stop codon. Stop codons are signals in messenger RNA that signal for the union of proteins to end.

Non-Stop Decay (NSD) Non-stop decay (NSD) degrades mRNAs that contain no stop codons.

NSD degrades two sorts of stop-codon free mRNAs, called nonstop and stop codon-less mRNAs, individually. Nonstop mRNAs are created by premature polyadenylation, in this manner they contain a polyA tail.

Non-Stop Decay (NSD) Non-stop decay (NSD) degrades mRNAs that contain premature stops.

In bacteria, a unique RNA that binds the A site of the ribosome and directs the addition of approximately 12 amino acids to the nascent peptide when no stop codon is present is called the Open Reading Frame
