Bookmark or Share- Gene Mutation: Definition, Causes, Types, Examples - SciencingGenetic mutations are slight alterations of DNA or RNA nucleotides, genes or chromosomes that may occur during replication or cell division. Random, uncorrected errors may be beneficial or harmful in relationship to evolution.
- 14.5: Types of Mutations - Biology LibreTextsGene mutations have varying effects on health, depending on where they occur and whether they alter the function of essential proteins. The types of mutations include: Silent mutation: Silent mutations cause a change in the sequence of bases in a DNA molecule, but do not result in a change in the amino acid sequence of a protein (Figure ...
- Mutation | Definition, Causes, Types, & Facts | Britannicamutation, an alteration in the genetic material (the genome) of a cell of a living organism or of a virus that is more or less permanent and that can be transmitted to the cell’s or the virus’s descendants. (The genomes of organisms are all composed of DNA, whereas viral genomes can be of DNA or RNA; see heredity: The physical basis of heredity.)
- Mutation - WikipediaMutation is the ultimate source of all genetic variation, providing the raw material on which evolutionary forces such as natural selection can act. Mutation can result in many different types of change in sequences. Mutations in genes can have no effect, alter the product of a gene, or prevent the gene from functioning properly or completely.
- Definition, Types, Examples and Quiz - Biology DictionaryIn biology, mutations refer to changes in chromosomes and genes, which typically manifest physically. The effect of a mutation can depend on the region in which the sequence of genetic material has been changed.
