Mutation (Edexcel IGCSE Biology: Double Science)
Revision Note
Mutations
- Mutations are rare, random changes that occur in the sequence of DNA bases in a gene or a chromosome
- Mutations can be inherited
- They occur continuously
- As the DNA base sequence determines the sequence of amino acids that make up a protein, mutations in a gene can sometimes lead to a change in the protein that the gene codes for
- Most mutations do not alter the protein or only alter it slightly so that its appearance or function is not changed
