Due to a random error by the aminoacyl tRNA synthetase, a tRNAVal was misloaded with Ile. What do you predict will result?

A. One protein will get Val inserted where Ile was supposed to go, leading to minor structural change in the protein.

B. One protein will get Ile inserted where Val was supposed to go, leading to major structural changes in the protein.

C. One protein will get Ile inserted where Val was supposed to go, leading to minor structural change in the protein.

D. The cell's proteins will get Ile and Val inserted in the wrong places, leading to major structural changes in the proteins.

Joslyn Parsons · Answer 1

The correct answer is option C.

Explanation:

Isoleucine and Valine both are amino acids that are branched, aliphatic and carrying aliphatic chain with alpha amino and alpha carboxylic acid group. These are presented within the protein.

As both are aliphatic and hydrophobic in nature so there would be no major effect on the particular protein due to the amino acid replacement. In the case of the in aromatic or aliphatic and hydrophobic and hydrophilic amino acids replacement most likely to get major structural changes in the protein.

Thus, the correct answer is - Option c.
