AJH Mutations REVIEW

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 are the three main types of mutations?

Back

Insertion, Deletion, Substitution.

Front

What is a substitution mutation?

Back

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

Front

What is an insertion mutation?

Back

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

Front

What is a deletion mutation?

Back

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

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.

Front

What is a frameshift mutation?

Back

A frameshift mutation occurs when base pairs are inserted or deleted, causing a shift in the reading frame of the genetic code.

Example of a substitution mutation: ATG CCA AAT changes to?

Back

ATG TCA AAT.
