What is a point mutation?

Back

A point mutation is when one nucleotide base is changed, affecting only one amino acid.

Front

What type of mutation is a missense mutation?

Back

A missense mutation is a type of mutation that results in a different amino acid being incorporated into a protein.

What are chromosomal mutations?

Back

Mutations that involve parts of or all of a chromosome.

Front

What is a deletion mutation?

Back

A deletion mutation is when one or more nucleotide bases are removed from the DNA sequence.

Front

What is an insertion mutation?

Back

An insertion mutation is when one or more nucleotide bases are added into the DNA sequence.

Front

What is a silent mutation?

Back

A silent mutation is a change in the DNA sequence that does not affect the amino acid sequence of a protein.

Front

What is the difference between a point mutation and a frameshift mutation?

Back

A point mutation changes a single nucleotide, while a frameshift mutation shifts the reading frame by inserting or deleting nucleotides.
