What is a base substitution mutation?

Back

A base substitution mutation is a type of mutation where one base in the DNA sequence is replaced by another.

Front

What is a base insertion mutation?

Back

A base insertion mutation occurs when one or more bases are added to the DNA sequence.

Front

What is a base deletion mutation?

Back

A base deletion mutation happens when one or more bases are removed from 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.

Front

Why is the order of amino acids important?

Back

The order of amino acids determines the shape and function of the protein.

Front

What is the result of a base substitution mutation?

Back

It can lead to a change in a single amino acid in a protein, potentially altering its function.

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 introduce genetic variation, which is essential for the process of natural selection.
