Types of Mutations Practice

Front

What is a mutation?

Back

A mutation is a change in the DNA sequence that can lead to changes in the structure and function of proteins.

Front

What is a substitution mutation?

Back

A substitution mutation occurs when one nucleotide in the DNA sequence is replaced by another nucleotide.

Front

What is an insertion mutation?

Back

An insertion mutation involves the addition of one or more nucleotides into a DNA sequence.

Front

What is a deletion mutation?

Back

A deletion mutation occurs when one or more nucleotides are removed from a DNA sequence.

Front

What is a frameshift mutation?

Back

A frameshift mutation is caused by insertions or deletions that change the reading frame of the genetic code.

Front

What is the effect of a substitution mutation?

Back

A substitution mutation can lead to a change in a single amino acid in a protein, potentially altering its function.

Front

What is the effect of an insertion mutation?

Back

An insertion mutation can disrupt the reading frame, leading to a completely different translation of the amino acid sequence.

Front

What is the effect of a deletion mutation?

Back

A deletion mutation can also disrupt the reading frame, resulting in a different amino acid sequence.

Front

What is an example of a frameshift deletion?

Back

Removing one nucleotide from a DNA sequence is an example of a frameshift deletion.

Front

What is an example of a substitution mutation?

Back

Changing one nucleotide in the DNA sequence, such as from A to G, is an example of a substitution mutation.
