What Is The Function Of Stop Codons? A stop codon is a trinucleotide sequence within a messenger RNA (mRNA) molecule that signals a halt to protein synthesis. What is the function of a stop codon quizlet? Stop codons signal the end of the amino acid chain. Compare/contrast: exons are sequences of a gene’s DNA that
What Is A Termination Signal? The prokaryotic chain termination signal is a hairpin structure at the end of every transcription unit (Fig. 16-7). The hairpin structure is created by an inverted hyphenated repeat that allows complementary base pairing to form a double helix. What happens at the termination signal? RNA polymerase will keep transcribing until
What Codons Are Termination Signals? What codons are termination signals? There are 3 STOP codons in the genetic code – UAG, UAA, and UGA. These codons signal the end of the polypeptide chain during translation. These codons are also known as nonsense codons or termination codons as they do not code for an amino acid.
