Explanation:
Detailed explanation-1: -So, the correct option is ‘It extends from one end of a tRNA molecule’.
Detailed explanation-2: -Hence, Option (b) i.e. A codon in mRNA is read in a non-contiguous fashion is the correct answer as it is not a true statement for genetic code.
Detailed explanation-3: -Which of the following statements regarding codons is true? Explanation: Every codon is composed of three RNA nucleobases, and codes for a specific amino acid; however, there can be multiple codons that code for one amino acid.
Detailed explanation-4: -The correct answer is option (A). Codons are three nucleotide long structures which code for amino acids in a polypeptide chain or protein molecule. The codons can be either in DNA or in RNA.
