Question

Section 39.2 discussed the mechanism by which threonyl-tRNA synthetase attaches threonine to the proper tRNA while preventing the attachment of the similar amino acids valine and serine. Using this as a model, explain how an isoleucyl-tRNA synthetase might prevent the incorrect addition of the similar amino acids leucine and valine to its target tRNA.
Valine could fit in the activation site.
[ Choose ] FALSE TRUE
Isoleucine could fit in the activation site.
[ Choose ] FALSE TRUE
Leucine could fit in the activation site.
[ Choose ] FALSE TRUE
Valine could fit in the editing site.
[ Choose ] FALSE TRUE
Isoleucine could fit in the editing site.
[ Choose ] FALSE TRUE
Leucine could fit in the editing site.

Answer 1

Explanation:

Answer 2

The prevention of incorrect addition of the similar amino acids leucine and valine to its target tRNA are:

A. Valine- false.

B. Isoleucine - true.

C. Leucine - false.

D. Valine - true.

E. Isoleucine - false.

What are amino acids?

Amino acid are the basic unit to make proteins. There are total 20 amino acids are present. They are made up of amino and carboxylate functional group.

Thus, the correct option is A. Valine- false.

B. Isoleucine - true.

C. Leucine - false.

D. Valine - true.

E. Isoleucine - false.

F. Leucine - true.
