What is a mutation?

Back

A mutation is a change in the DNA sequence of an organism, which can lead to changes in the organism's traits.

Front

What is an inversion mutation?

Back

An inversion mutation occurs when a segment of DNA is reversed end to end, altering the gene sequence.

Front

What is a point mutation?

Back

A point mutation is a change in a single nucleotide base in the DNA sequence, which can affect one amino acid in a protein.

Front

What is a frameshift mutation?

Back

A frameshift mutation occurs when nucleotides are added or removed from the DNA sequence, causing a shift in the reading frame.

Front

What is a deletion mutation?

Back

A deletion mutation is a type of frameshift mutation where one or more nucleotide bases are removed from the DNA sequence.

Front

What is a substitution mutation?

Back

A substitution mutation is when one nucleotide base is replaced by another, potentially altering the amino acid sequence.

Front

What is a silent mutation?

Back

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

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 translocation in genetics?

Back

Translocation is a mutation where a segment of DNA is moved from one location to another within the genome.

Front

What is the significance of mutations in evolution?

Back

Mutations are a source of genetic variation, which can lead to evolution as organisms adapt to their environments.
