What is a mutation?

Back

A mutation is a change in the DNA sequence of an organism's genome.

Front

What are the three main types of mutations?

Back

The three main types of mutations are substitution, insertion, and deletion.

Front

What is a substitution mutation?

Back

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

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 the effect of a mutation on protein synthesis?

Back

Mutations can alter the amino acid sequence of proteins, potentially affecting their function.

Front

What is a mutagen?

Back

A mutagen is an agent that causes changes in the DNA sequence, leading to mutations.

Front

How can reducing exposure to mutagens affect health?

Back

Reducing exposure to mutagens can decrease the risk of mutations that may lead to diseases like cancer.

Front

What is selective breeding?

Back

Selective breeding is the process of choosing specific organisms to reproduce based on desired traits.

Front

Give an example of selective breeding.

Back

A person pollinates two white rose plants to only create white roses.
