Mutations and Their Effects

Which mutation does not change the amino acid sequence?

• Frameshift mutation

• Silent mutation

• Missense mutation

• Nonsense mutation

Which mutation type is least likely to affect protein function?

• Frameshift mutation

• Silent mutation

• Missense mutation

• Nonsense mutation

Which mutation changes one amino acid to another?

• Silent mutation

• Missense mutation

• Frameshift mutation

• Nonsense mutation

What is the effect of a silent mutation on the protein?

• It changes the protein structure

• It introduces a stop codon

• It has no effect on the protein

• It shifts the reading frame

Which of the following is NOT a possible outcome of a base-pair substitution?

• Silent mutation

• Missense mutation

• Nonsense mutation

• Frameshift mutation

What is a base-pair substitution that results in a shorter protein called?

• Missense

• Nonsense

• Silent

• Frameshift

What is the primary effect of a frameshift mutation?

• No change in protein

• String of incorrect amino acids

• Enhanced protein function

• Silent mutation

What is the effect of a frameshift mutation causing immediate nonsense?

• Leads to a longer amino acid sequence

• Leads to truncation of the amino acid sequence

• Has no effect on the amino acid sequence

• Causes a duplication of the amino acid sequence

What does the term "nonsense" refer to in the context of frameshift mutations?

• A mutation that enhances protein function

• A mutation that results in a stop codon

• A mutation that has no effect

• A mutation that duplicates the sequence

What is a chromosomal mutation?

• A change in the DNA sequence

• A change in the chromosomes

• A change in the protein structure

• A change in the cell membrane
