In bacteria, how many tRNA molecules are necessary to produce an entire polypeptide containing 120 amino acids

This sounds like a trick question..


120 tRNA if only one is used for each amino acid and doesn't re-charge with another


20-40 different tRNA if one of each is used and can be re-used without counting as another tRNA molecule


20 if only one of each tRNA coding for a different amino acid is used and then can re-charge without counting again

In bacteria, how many tRNA molecules are necessary to produce an entire polypeptide containing 120 amino acids
One, if it the same AA over and over again.

Reply:as many as 40. it can be less if one t-rna happens to be recharged and used over again, but that's highly unlikely.
Reply:Well, one tRNA carries three *base* recognition sites and carries one *amino acid* so, 120 I should think :/
