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?

Answer 1

Silent Mutation

Explanation:

• Mutations are changes in a DNA sequence, and they can occur due to radiation or other types of DNA damage. If mutations occur in the part of a gene that encodes a protein (the coding region of a gene), they can change the amino acid sequence of that protein
• But not always; a silent mutation is a type of mutation in the coding region of a gene that doesn't actually change the amino acid sequence of the protein that is made
• A point mutation is a change in one nucleotide or base pair of a DNA sequence. An example would be if a C in the DNA code was changed to a T
• Point mutations can happen anywhere along a DNA sequence, Mutations in the coding region of DNA can directly affect the amino acid sequence of the protein product
