\begin{figure}[h!] \centering \includegraphics[width=0.5\linewidth]{Screenshot 20250115 144456.png} % Replace with the correct path to your image \caption{Diagram} \label{Diagram} \end{figure} (i) Identify the polarity from ‘X’ to ‘Y’ in the mRNA segment shown. Mention how many more amino acids can be added to the polypeptide that is being translated and why.

Hint:

mRNA’s polarity determines the direction of translation, with the ribosome reading it from 5’ to 3’.

Answer 1

Polarity: 5’ to 3’ direction. Number of additional amino acids: Depends on the number of codons left untranslated on the mRNA. Reason: Each codon corresponds to one amino acid, and translation stops when a stop codon is encountered.
