Mutations cause changes in the genetic code that lead to genetic variation and the potential to develop disease. Gene mutations can be generally categorized into two types: point mutations and base-pair insertions or deletions. Point mutations are the most common type of gene mutation. Also called a base-pair substitution, this type of mutation changes a single nucleotide base pair.
This type of analysis is also used in the type of DNA testing that is used in crime labs or used to determine paternity. POINT MUTATIONS, often caused by chemicals or malfunction of DNA replication, exchange a single nucleotide for another.oint mutations that occur within the protein coding region of a gene may be classified into three kinds... A. nonsense mutations: code for a stop, which can truncate the protein. B. missense mutations: code for a different amino acid. C. silent mutations: code for the same amino acid.
