What is a nonsense mutation?

Back

A type of substitution mutation that results in a premature stop codon, leading to incomplete protein synthesis.

Front

What is a silent mutation?

Back

A mutation that does not affect the protein function, often because it does not change the amino acid sequence.

Front

What is a missense mutation?

Back

A type of mutation where a single nucleotide change results in a codon that codes for a different amino acid.

Front

What is a frameshift mutation?

Back

A mutation caused by insertions or deletions that shift the reading frame of the genetic code.

Front

What is duplication in genetics?

Back

A mutation where a piece of a chromosome is copied and remains within the chromosome.

Front

What is deletion in genetics?

Back

A mutation where a section of DNA is lost or removed from the chromosome.

Front

What is translocation in genetics?

Back

A mutation where a segment of DNA is moved from one location to another, either within the same chromosome or to a different chromosome.

Front

What is an insertion mutation?

Back

A mutation where one or more nucleotide bases are added into a DNA sequence.

Front

What is the impact of a nonsense mutation on protein synthesis?

Back

It leads to the production of a truncated protein, which is often nonfunctional.

Front

How does a silent mutation affect protein synthesis?

Back

It does not change the amino acid sequence, so the protein remains functional.
