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 main types of mutations?

Back

The main types of mutations are substitutions, insertions, and deletions.

Front

What is a substitution mutation?

Back

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

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 deletion mutation?

Back

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

Front

What is a frameshift mutation?

Back

A frameshift mutation is a genetic mutation caused by insertions or deletions that shift the reading frame of the genetic message.

Front

How do insertions and deletions affect protein synthesis?

Back

Insertions and deletions can lead to frameshift mutations, which can alter the entire amino acid sequence downstream of the mutation.

Front

What is the difference between a silent mutation and a missense mutation?

Back

A silent mutation does not change the amino acid sequence, while a missense mutation results in a different amino acid being incorporated into the protein.

Front

What is the significance of mutations in evolution?

Back

Mutations are a source of genetic variation, which is essential for evolution and natural selection.

Front

What is a point mutation?

Back

A point mutation is a change in a single nucleotide base pair in the DNA sequence.
