MUTATIONS

What is a mutation?

Back

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

Front

What are the two main types of mutations?

Back

The two main types of mutations are gene mutations (affecting a single gene) and chromosomal mutations (affecting whole chromosomes).

Front

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 gene.

Front

What is a point mutation?

Back

A point mutation is a change in a single nucleotide in a gene sequence.

Front

What is the primary cause of a frameshift mutation?

Back

Insertion or deletion of nucleotides.

Front

Can mutations in somatic cells be passed to offspring?

Back

No. Only mutations that occur in the gametes (sex cells) are passed on to the offspring.

Front

What is a substitution mutation?

Back

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

Front

What is an example of a point mutation?

Back

Substitution of a single nucleotide.

Front

What is a silent mutation?

Back

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

Front

What is a missense mutation?

Back

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