Study the mRNA segment given above, which is to be completely translated into a polypeptide chain.
The codons for ‘a’ and ‘b’ are:
Options:
Answer:
C
Solution:
The start codon is the first codon of a messenger RNA (mRNA) transcript translated by a ribosome. The start codon always codes for methionine in eukaryotes and a modified Met (fMet) in prokaryotes. The most common start codon is AUG.
A stop codon (or termination codon) is a nucleotide triplet within messenger RNA that signals a termination of translation. The stop codons do not have amino acids. In RNA, the three termination codons are UAG ("amber"), UAA ("ochre"), and UGA ("opal").
