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.
Polarity: 5’ to 3’.
Number of additional amino acids: Determined by the number of codons left untranslated on mRNA.
Explanation: Each codon codes for one amino acid until a stop codon is reached.
