a. Identify the polarity from a to a′ in the given diagram and mention how many more amino acids are expected to be added to this polypeptide chain. b. Mention the DNA sequence coding for serine and the anticodon of tRNA for the same amino acid. c. Why are some untranslated sequence of bases seen in mRNA coding for a polypeptide? Where exactly are they present on mRNA? |

Answer» a. Polarity from a to a' is 5'→ 3'. No more amino acid will be added to this polypeptide chain. b. TCA; anticodon is UCA. c. The untranslated sequence of bases are required for efficient translation process. They are present before the start codon at the 5'-end and after the stop codon at 3'-end. |
