Question

A genetic mutation involving a single base causes an error that affects the sequence of the next 500 amino acids in a protein. Which type of mutation could have produced this type of error in the protein?

A)Silent
B)Nonsensse
C)frame-shift

Answer 1

The answer is C. Frame-shift

Answer 2

C)frame-shift

Step-by-step explanation:

Since the protein-encoding DNA is divided into codons of three bases each, insertions and deletions can alter a gene to the point that its message loses its meaning. These changes are called the reading frame offset.

For example, consider the phrase: "The fat cat sat". Each letter represents a codon. If we delete the first letter and try to analyze the sentence in the same way, it doesn't make sense. In frame-shift, a similar error occurs at the molecular level, causing the codons to be analyzed incorrectly. This usually produces useless proteins.
