Front

What is a duplication mutation?

Back

A duplication mutation occurs when a segment of DNA is copied, resulting in multiple copies of that segment.

Front

What is a translocation mutation?

Back

A translocation mutation involves the rearrangement of parts between nonhomologous chromosomes.

Front

What is a frameshift mutation?

Back

A frameshift mutation occurs when nucleotides are inserted or deleted from the DNA sequence, altering the reading frame.

Front

What is a point mutation?

Back

A point mutation is a mutation that involves a change in a single nucleotide in the DNA sequence.

Front

What are insertions in the context of mutations?

Back

Insertions are mutations where one or more nucleotides are added to the DNA sequence.

Front

What are deletions in the context of mutations?

Back

Deletions are mutations where one or more nucleotides are removed from the DNA sequence.

Front

What is a substitution mutation?

Back

A substitution mutation is a type of mutation where one nucleotide is replaced by another nucleotide.

Front

What is the difference between a deletion and a duplication mutation?

Back

A deletion mutation removes a segment of DNA, while a duplication mutation creates an extra copy of a segment.

Front

What is an inversion mutation?

Back

An inversion mutation occurs when a segment of DNA is reversed within the chromosome.
