what type of mutation is mutated dna sequence #2? a point substitution b insertion (frameshift mutation) c deletion (frameshift mutation) question 10 0.5 points what effect does this mutation have on the protein, compared to the original? a no change b 1 amino acid changed c premature stop signal last saved 3:18:08 pm questions filter (15)

Explanation:

Without seeing the actual DNA sequence #2, we can define the mutation types. A point - substitution is a single - base change. Insertion and deletion (frameshift mutations) change the reading frame of the genetic code. For the effect on the protein, a point - substitution can change one amino acid, a frameshift mutation can cause a premature stop signal or completely alter the amino - acid sequence downstream. Since no sequence is given, we assume basic knowledge application. If it's a point - substitution, usually 1 amino acid is changed.

Answer:

For the first question: Without the sequence, we can't be sure, but if we assume a common scenario, a point - substitution is a likely simple mutation type. So A. Point substitution.
For the second question: If it's a point - substitution, 1 amino acid is changed. So B. 1 amino acid changed.
