प्रश्न
How many amino acids will be there in the polypeptide chain formed on the following mRNA?
5'GCCACAUGGAGAUGACGACAAAAUUUUACUAGAAAA3'

उत्तर
The polypeptide chain will have 8 amino acids.
Explanation:
-
Identify the Start Codon:
- The sequence AUG is the start codon, initiating translation.
-
Divide into Codons After Start Codon:
- Codons: AUG GAG AUG ACG ACA AAA UUU UAC
- UAG is a stop codon, so translation stops here.
-
Count the Amino Acids:
- The 8 codons before the stop codon translate into 8 amino acids.
Thus, the polypeptide chain contains 8 amino acids before termination.
