What is a DNA mutation?

Back

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

Front

What is a deletion mutation?

Back

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

Front

What is an insertion mutation?

Back

An insertion mutation occurs when one or more nucleotides are added to the DNA sequence.

Front

What is a substitution mutation?

Back

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

What base pairs with Adenine (A) in DNA?

Back

Thymine (T) pairs with Adenine (A) in DNA.

Front

What base pairs with Cytosine (C) in DNA?

Back

Guanine (G) pairs with Cytosine (C) in DNA.

Front

What is a translocation mutation?

Back

A translocation mutation occurs when a segment of DNA is moved from one location to another within the genome.

Front

What is an inversion mutation?

Back

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

Front

What is a silent mutation?

Back

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