Question

Suppose that the human insulin protein that was produced by the bacteria was much shorter than it should be. Upon further investigation, it was found that the DNA of the human insulin gene had a mutation while in the bacterial cells.
What type of mutation could not result in these observations?
Group of answer choices
nucleotide insertion silent mutation
nonsense mutation nucleotide deletion

Answer 1

Answer:

Silent mutation.

Explanation:

A silent mutation usually does not affect the protein produced by the translation of a given gene, it means, it will not affect the aminoacid sequence of the protein, since the genetic code is degenerated.

A Nonsense mutation will derive in the formation of an early STOP codon, so, the protein will be truncated (shorter than it should be).

It is important to notice that nucleotide insertion and deletion COULD derive also in the formation of a stop codon, but not necessarily, since it can just move the reading frame, and of course it will derive in a different protein.
