Gene Mutations

Front

What is a Point Mutation?

Back

A type of mutation where one nucleotide base is changed, affecting only one amino acid in the protein sequence.

Front

What are Mutations?

Back

Changes in a gene, group of genes, or chromosome that result in a change in the proteins produced.

Front

What is a Frameshift Mutation?

Back

A mutation caused by the insertion or deletion of a nucleotide base, shifting the entire DNA sequence and altering the entire protein.

Front

What is an Insertion Mutation?

Back

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

Front

What is a Silent Mutation?

Back

A substitution mutation that has no effect on the amino acid sequence of a protein.

Front

What is a Substitution Mutation?

Back

A mutation where one nucleotide base is replaced by another, which may or may not affect the amino acid sequence.

Front

What is a Deletion Mutation?

Back

A type of mutation where one or more nucleotide bases are removed from the DNA sequence.

Front

What is Translocation in genetics?

Back

A mutation where a segment of DNA is moved from one location to another, which can disrupt gene function.

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 the role of DNA in mutations?

Back

DNA carries the genetic information, and mutations can alter this information, leading to changes in traits.
