Mutations Review

Front

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

1. Substitution Mutation 2. Deletion Mutation 3. Insertion Mutation

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 a deletion mutation?

Back

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

Front

What is an insertion mutation?

Back

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

Front

How can mutations be beneficial?

Back

Mutations can provide advantages that help organisms adapt to their environment, potentially leading to evolutionary changes.

Front

What is the role of the nucleus in relation to DNA?

Back

The nucleus is the organelle where DNA is housed and protected in eukaryotic cells.

Front

Can mutations lead to genetic disorders?

Back

Yes, some mutations can disrupt normal gene function and lead to genetic disorders.

Front

What is the significance of mutations in evolution?

Back

Mutations introduce genetic variation, which is essential for natural selection and evolution.

Front

What is a frameshift mutation?

Back

A frameshift mutation occurs when base pairs are inserted or deleted, altering the reading frame of the genetic code.
