Question

If each amino acid weighs $100$ mass units, what is the weight (in mass units) of the protein, molecules synthesis from a mRNA molecule which is $600$ base long?

• A. $2000$
• B. $6000$
• C. $20000$
• D. $60000$

Answer 1

The correct option is C $20000$

It is given that each amino acid weighs 100 mass units. Each amino acid is consists of a triplet. It means it has 3 base pairs. If a protein is having 600 base pairs, it has approximately 200 amino acids. Hence, the weight of 200 acid will be 200 x 100 = 20000 mass units.

Thus, the correct answer is '20000.'
