DNA Mutations

Front

What is a silent mutation?

Back

A type of substitution mutation where no amino acids change in the protein sequence.

Front

What causes a frameshift mutation?

Back

Frameshift mutations are caused by insertions or deletions of nucleotides in the DNA sequence.

Front

What is a substitution mutation?

Back

A mutation where one nucleotide is replaced by another, potentially changing one amino acid in the protein.

Front

What is a deletion mutation?

Back

A mutation where one or more nucleotides are removed from the DNA sequence.

Front

What is an insertion mutation?

Back

A mutation where one or more nucleotides are added to the DNA sequence.

Front

What is the difference between missense and nonsense mutations?

Back

Missense mutations result in a different amino acid, while nonsense mutations create a premature stop codon.

Front

What is a frameshift mutation?

Back

A mutation that shifts the reading frame of the genetic code, altering all subsequent amino acids.

Front

What is the significance of the genetic code?

Back

The genetic code is a set of rules that defines how sequences of nucleotides translate into amino acids.

Front

What is a point mutation?

Back

A mutation that affects a single nucleotide in the DNA sequence.

Front

What is a transversion mutation?

Back

A type of point mutation where a purine is replaced by a pyrimidine or vice versa.
