GCIDE

  1. mutationnoun

    (Biol.) (a) As now employed (first by de Vries), a cellular process resulting in a sudden inheritable variation (the offspring differing from its parents in some well-marked character or characters) as distinguished from a gradual variation in which the new characters become fully developed only in the course of many generations. The occurrence of mutations, the selection of strains carrying mutations permitting enhanced survival under prevailing conditions, and the mechanism of hereditary of the characters so appearing, are well-established facts; whether and to what extent the mutation process has played the most important part in the evolution of the existing species and other groups of organisms is an unresolved question. (b) The result of the above process; a suddenly produced variation. Mutations can occur by a change in the fundamental coding sequence of the hereditary material, which in most organisms is DNA, but in some viruses is RNA. It can also occur by rearrangement of an organism's chromosomes. Specific mutations due to a change in DNA sequence have been recognized as causing certain specific hereditary diseases. Certain processes which produce variation in the genotype of an organism, such as sexual mixing of chromosomes in offspring, or artificially induced recombination or introduction of novel genetic material into an organism, are not referred to as mutation.

Wikipedia

  1. Mutation

    In biology, a mutation is an alteration in the nucleic acid sequence of the genome of an organism, virus, or extrachromosomal DNA. Viral genomes contain either DNA or RNA. Mutations result from errors during DNA or viral replication, mitosis, or meiosis or other types of damage to DNA (such as pyrimidine dimers caused by exposure to ultraviolet radiation), which then may undergo error-prone repair (especially microhomology-mediated end joining), cause an error during other forms of repair, or cause an error during replication (translesion synthesis). Mutations may also result from insertion or deletion of segments of DNA due to mobile genetic elements.Mutations may or may not produce detectable 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. Mutation 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. Mutations can also occur in non-genic regions. A 2007 study on genetic variations between different species of Drosophila suggested that, if a mutation changes a protein produced by a gene, the result is likely to be harmful, with an estimated 70% of amino acid polymorphisms that have damaging effects, and the remainder being either neutral or marginally beneficial. Due to the damaging effects that mutations can have on genes, organisms have mechanisms such as DNA repair to prevent or correct mutations by reverting the mutated sequence back to its original state.

  1. mutation

    A 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. These changes can occur in a single DNA building block or large segments of chromosomes. They can lead to variations among species, enable evolution, cause diseases and conditions, or have no significant effect. Mutations can occur spontaneously or as a result of exposure to specific environmental factors.

Webster Dictionary

  1. Mutationnoun

    change; alteration, either in form or qualities

  2. Etymology: [L. mutatio, fr. mutare to change: cf. F. mutation. See Mutable.]

  1. Mutation

    In genetics, a mutation is a change of the nucleotide sequence of the genome of an organism, virus, or extrachromosomal genetic element. Mutations result from unrepaired damage to DNA or to RNA genomes, from 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 discernable changes in the observable characteristics of an organism. Mutations play a part in both normal and abnormal biological processes, including evolution, cancer, and the development of the immune system. 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 can also occur in nongenic regions. One study on genetic variations between different species of Drosophila suggests that if a mutation changes a protein produced by a gene, the result is likely to be harmful, with an estimated 70 percent of amino acid polymorphisms having damaging effects, and the remainder being either neutral or weakly beneficial. Due to the damaging effects that mutations can have on genes, organisms have mechanisms such as DNA repair to prevent or correct mutations.

    Any detectable and heritable change in the genetic material that causes a change in the GENOTYPE and which is transmitted to daughter cells and to succeeding generations.

Examples of mutation in a Sentence

  1. Otis Brawley:

    Over the past 20 years we are learning of a number of genes that can have a mutation. Some change our treatment.

  2. Bidens First 100 DaysHere:

    The fundamental principle of getting people vaccinated as quickly and as efficiently as you possibly can will always be the best way to prevent the further evolution of any mutant, because when you do that, you prevent replication, and replication is essential for mutation.

  3. Kirill Dmitriev:

    Sputnik was the first in the world to suggest that the two shots should be different to give a stronger and longer immune response, more mutation-proof, so what others are starting to do with this kind of trial is to follow our steps.

  4. Zachary Lippman:

    We have been eating mutations in plants and animals since humans started to improve crops thousands of years ago, that's a random process and took thousands of years. With gene editing, Zachary Lippman're now just making one mutation in one gene in the simplest sense.

  5. David Tester:

    Having this genetic biomarker, we can now very easily test any individual for the presence of the mutation, having that ability can potentially save lives.
