The substitution mutation is ATG TCA AAT.

Front

Which mutation results in the loss or addition of a single nucleotide, changing the DNA triplets?

Back

A frameshift mutation results in the loss or addition of a single nucleotide.

Front

What is a mutation?

Back

A mutation is a change in the DNA sequence that can lead to changes in the structure and function of proteins.

Front

Define a missense mutation.

Back

A missense mutation is a type of mutation that results in a different amino acid being incorporated into a protein.

Front

What is a nonsense mutation?

Back

A nonsense mutation is a mutation that creates a premature stop codon in the DNA sequence.

Front

Explain what a silent mutation is.

Back

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

Front

What is the role of nucleotides in DNA?

Back

Nucleotides are the building blocks of DNA, consisting of a sugar, a phosphate group, and a nitrogenous base.
