Answer:
The correct answer is c. 10
Step-by-step explanation:
Each amino acid is coded by a particular codon set made up of three nucleotides which is called triple codon. So three codons or nucleotides are required to code for a single amino acid.
Therefore a gene composed of 30 nucleotide can only code for 10 amino acids and not more than that. tRNA is the molecule which has complementary codons called anticodon which adds amino acids during the translation process. Therefore the correct answer is c. 10.
