Question

Which of the following best explains how a single nucleotide substitution can cause hemoglobin molecules to chain together instead of forming the appropriate protein product?

The mutation causes the removal of an amino acid, which results in a different protein product
. The mutation causes the same amino acid to be repeated multiple times in the protein product, which results in a linear protein structure.
The mutation causes the wrong amino acid to be incorporated into the protein product, which results in improper protein folding.
The mutation causes the protein product to be lengthened due to an increased number of amino acids being incorporated.

Answer 1

The correct option is this: THE MUTATION CAUSES THE WRONG AMINO ACID TO BE INCORPORATED INTO THE PROTEIN PRODUCT, WHICH RESULTS IN IMPROPER FOLDING.
There are different type of mutation, one of them is substitution mutation. Substitution mutation occurs when one nucleotide is exchanged for another during the process of nucleotide incorporation. Such a change will result in change in the function of the protein that is been formed.
