Mutation Summary
Robin Cook

Genetic Variation in a Population Genetic variation in a population describes the existence in that population of different alleles, or alternative forms, for a given gene. The presence of genetic var... Read more

Mutation A mutation is any heritable change in the genome of an organism. For a population, heritable mutations provide the source of genetic variation, without which evolution could not occur: If all... Read more

Gene Mutation Gene mutation is a sudden change in the DNA making up an individual gene. Gene mutation is a fairly infrequent event, although its occurrence can be speeded up by the action of radiation... Read more

Mutation Mutation is an alteration in an organism's genes. The mutation is carried to the organism's offspring, so the offspring may look or act different from its ancestors. Mutations may be benefici... Read more

Amber, Ocher, and Opal Mutations Amber, ocher and opal mutations are specific types of nonsense mutations that result in production of protein chain terminating codons that prematurely stop protein sy... Read more

Gene Mutations and Genetic Change In a strict sense, mutations are changes in genes not caused by genetic recombination. A change in the base sequence of DNA, for example, represents a mutational chan... Read more

Mutation A mutation is a sudden change in DNA (deoxyribonucleic acid), the genetic material of life. Mutation is a major evolutionary force that results from wide range of factors and that carries a w... Read more

Radiation Mutagenesis Mutations are caused by DNA damage and genetic alterations that may occur spontaneously at a very low rate. The frequency of these mutations can be increased by using special age... Read more

Spontaneous Mutations and Reversions Mutations and reversions are events that change the expression of traits of an organism. They change the organism's phenotype. The change can result from a change ... Read more

Mutations A mutation is any change in genetic material that is passed on to the next generation. The process of acquiring change in genetic material forms the fundamental underpinning of evolution. Mu... Read more

Mutation A mutation is an abrupt change in genes or chromosomes that affects an organism morphologically. Mutations can occur spontaneously or be induced by environmental factors, and, on occasion, th... Read more
