Gene Mutations

Front

What is a Frameshift Mutation?

Back

A type of mutation where a nucleotide base is inserted or deleted, shifting the entire DNA sequence and changing the entire protein.

Front

What is a Substitution Mutation?

Back

A point mutation where one nucleotide base replaces an original nucleotide base.

Front

What causes mutations?

Back

Mutations can be caused by mistakes in DNA replication or environmental substances.

Front

What is an Insertion Mutation?

Back

A frameshift mutation where a nucleotide base is added to the DNA sequence.

Front

What is a Deletion Mutation?

Back

A frameshift mutation where a nucleotide base is removed from the DNA sequence.

Front

What is a Silent Mutation?

Back

A mutation that does not change the amino acid sequence of a protein.

Front

What is a Chromosomal Mutation?

Back

A mutation that involves changes in the structure or number of chromosomes.

Front

What is Translocation in genetics?

Back

A mutation where a segment of DNA is moved from one location to another within the genome.

Front

What is a Point Mutation?

Back

A mutation that affects a single nucleotide in the DNA sequence.

Front

What is the role of environmental substances in mutations?

Back

Environmental substances, such as chemicals or radiation, can cause changes in DNA that lead to mutations.
