Gene Mutations

Front

What is a frameshift mutation?

Back

A frameshift mutation is a genetic mutation caused by the insertion or deletion of a nucleotide in a DNA sequence, which shifts the reading frame of the genetic code.

Front

What is an insertion mutation?

Back

An insertion mutation is a type of mutation where one or more nucleotide bases are added to the DNA sequence.

Front

What is a deletion mutation?

Back

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

Front

What is a substitution mutation?

Back

A substitution mutation is a type of mutation where one nucleotide base is replaced by another in the DNA sequence.

Front

What is a silent mutation?

Back

A silent mutation is a type of substitution mutation that does not change the amino acid sequence of the protein.

Front

What is an expressed mutation?

Back

An expressed mutation is a mutation that results in a change in the amino acid sequence of a protein.

Front

What is a translocation mutation?

Back

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

Front

How can mutations benefit organisms?

Back

Mutations can benefit organisms by providing genetic variations that may enhance their ability to survive and adapt to their environment.

Front

What is the role of amino acids in mutations?

Back

Amino acids are the building blocks of proteins, and mutations can change the sequence of amino acids, potentially altering protein function.

Front

What is the significance of the genetic code?

Back

The genetic code is the set of rules by which information encoded in genetic material is translated into proteins, determining the traits of an organism.
