Question

The solutions that i have gotten so far are wrong. Any asurrant takers out there. Thank You all in advance!!!

Practice Problem 56 Below is a partial mRNA sequence. Use it to answer the following questions. 5'-GccGAUcGAAcU-3' Part C The amino acids in the original partial sequence (N-term-... P-l-E . -c-term) have little to no impact on protein structure and function. However the amino acid sequence near the c-terminal end of the protein is required for normal function. Any amino acid changes in this region of the protein will result in a nonfunctional protein. Given this information, which reversion mutation in the gene would restore the normal function of the protein?

Explanation / Answer

in part C: answer is 2 & 4

mutant synthetase gene allows histidine tRNA to be charged with asparagine but sometimes this tRNA could deliver asparagine in place of histidine to other proteins where histidine residue was important to functiom of the protein and growth.

mutant synthetase gene allows histidine tRNA to be charged with asparagine therefore, histidine could not be present in any protein. if histidine was important to function in various other proteins. growth may not be completely restored.

in part C: insertion of 1bp in proline and insertion of 4 bp in proline will restore the function
