mRNA to Amino Acid Translation — NEET Biology
📚 Practice ConceptIf following is the sequence of nucleotides in mRNA, predict the sequence of amino acid coded by it (take help of the checkerboard):
Match the following with their correct outcomes or properties of the genetic code: Column I A. Amino acid sequence: Met–Phe–Phe–Phe–Phe–Phe–Phe B. mRNA sequence: AUG UUU UUC UUC UUU UUU GUG C. Property of genetic code: More than one codon can code for the same amino acid D. Property of genetic code: Code is read in a continuous manner without punctuation Column II 1. Degeneracy of the genetic code 2. Contiguous (commaless) nature of the code 3. mRNA sequence: AUG UUU UUC UUC UUU UUU GUG 4. Amino acid sequence: Met–Phe–Phe–Phe–Phe–Phe–Phe
View solution & NCERT explanation
Correct answer: D — A–4, B–3, C–1, D–2
A (amino acid sequence Met–Phe–Phe–Phe–Phe–Phe–Phe) corresponds to 4. B (mRNA AUG UUU UUC UUC UUU UUU GUG) corresponds to 3. C shows degeneracy, since Phe has more than one codon (UUU and UUC) → 1. D shows commaless/contiguous nature, codons read without punctuation → 2.
