What is a frameshift mutation?

Back

A frameshift mutation is caused by the insertion or deletion of nucleotides, which alters the reading frame of the genetic code.

What is a nonsense mutation?

Back

A nonsense mutation is a type of mutation that creates a premature stop codon in the protein sequence, leading to incomplete proteins.

What is a missense mutation?

Back

A missense mutation is a change in a single nucleotide that results in the substitution of one amino acid for another in the protein.

What is translocation in genetics?

Back

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

What is crossing over?

Back

Crossing over is a process during meiosis where homologous chromosomes exchange genetic material, leading to genetic diversity.
