📖 NCERT Source

Now try the opposite. Following is the sequence of amino acids coded by an mRNA. Predict the nucleotide sequence in the RNA: Met-Phe-Phe-Phe-Phe-Phe-Phe Do you face any difficulty in predicting the opposite? Can you now correlate which two properties of genetic code you have learnt?

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
