Mutations

Front

What is a mutation?

Back

A mutation is a change in the DNA sequence of an organism's genome.

Front

What is a substitution mutation?

Back

A substitution mutation is a type of mutation where one nucleotide base is replaced by another.

Front

What is a silent mutation?

Back

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

Front

What is an inversion mutation?

Back

An inversion mutation occurs when a segment of DNA is reversed end to end.

Front

What is a point mutation?

Back

A point mutation is a mutation that affects a single nucleotide, resulting in a change in one amino acid.

Front

What is a frameshift mutation?

Back

A frameshift mutation occurs when nucleotides are inserted or deleted from the DNA sequence, altering the reading frame.

Front

Why are insertion mutations harmful?

Back

Insertion mutations can disrupt the normal reading frame of the genetic code, leading to significant changes in the resulting protein.

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 duplication mutation?

Back

A duplication mutation occurs when a segment of DNA is copied, resulting in multiple copies of that segment.

Front

What is translocation in genetics?

Back

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