Determine the number of i-RNA and t-RNA molecules involved in the synthesis of a protein molecule, which consists of 900 amino acids. How many nucleotides of m-RNA determines the primary structure of the molecule of this protein?
1. In the synthesis of one protein molecule, one molecule of i-RNA is involved;
2. One t-RNA molecule delivers one amino acid molecule to the ribosome, therefore, 900 amino acids deliver 900 t-RNA molecules;
3. Each amino acid corresponds to one triplet – 3 nucleotides, and 900 amino acids corresponds to 2700 nucleotides.
