A Mutation occurs when a DNA gene is damaged or changed in such a way as to alter the genetic message carried by that gene.
A gene mutation is a permanent alteration in the DNA sequence that makes up a gene, such that the sequence differs from what is found in most people. Mutations range in size; they can affect anywhere from a single DNA building block (base pair) to a large segment of a chromosome that includes multiple genes.  Definition. A Mutation occurs when a DNA gene is damaged or changed in such a way as to alter the genetic message carried by that gene. A Mutagen is an agent of substance that can bring about a permanent alteration to the physical composition of a DNA gene such that the genetic message is changed.  If a mutation occurs in the genome of a gamete, the mutation may be transmitted to later generations. mutate, v., mutational adj. (1) The process by which genes undergo a permanent and heritable change in nucleotide sequence that differs from either parental haploid contribution to the progeny.oint mutation a mutation resulting from a change in a single base pair in the DNA molecule. somatic mutation a genetic mutation occurring in a somatic cell, providing the basis for a mosaic condition. (biology) an organism that has characteristics resulting from chromosomal alteration. mutation, genetic mutation, chromosomal mutation (noun). (genetics) any event that changes genetic structure; any alteration in the inherited nucleic acid sequence of the genotype of an organism. A change in the genes or chromosomes of an organism. Mutations occurring in the reproductive cells, such as an egg or sperm, can be passed from one generation to the next. Most mutations have harmful effects, but some can increase an organism's ability to survive.n alteration or change, as in nature, form, or quality. 3. Genetics. a. A change in the nucleotide sequence of the genome of an organism or virus, sometimes resulting in the appearance of a new character or trait not found in the parental type. In biology, a mutation is a permanent change of the nucleotide sequence of the genome of an organism, virus, or extrachromosomal DNA or other genetic elements. Mutations may or may not produce discernible changes in the observable characteristics (phenotype) of an organism. Mutations play a part in both normal and abnormal biological processes including: evolution, cancer, and the development of the immune system, including junctional diversity. Mutations result from damage to DNA which is not repaired, errors in the process of replication, or from the insertion or deletion of segments of DNA by mobile genetic elements. Mutations may or may not produce discernible changes in the observable characteristics (phenotype) of an organism. Mutations play a part in both normal and abnormal biological processes including: evolution, cancer, and the development of the immune system, including junctional diversity. DNA and Mutations. by the Understanding Evolution team. A mutation is a change in DNA, the hereditary material of life. An organism's DNA affects how it looks, how it behaves, and its physiology. So a change in an organism's DNA can cause changes in all aspects of its life The word mutation means a change in the genetic composition of a cell. Mutations can be divided into two main groups. The first group is gene mutations. These are chemical changes in the DNA [DNA: The material inside the nucleus of cells, carrying genetic information.DNA stands for Deoxyribonucleic Acid.] of the cell. Mutation can result in several different types of change in sequences. Mutations in genes can either have no effect, alter the product of a gene, or prevent the gene from functioning properly or completely. Mutations may or may not produce discernible changes in the observable characteristics (phenotype) of an organism. Mutations play a part in both normal and abnormal biological processes including: evolution, cancer, and the development of the immune system, including junctional diversity.
