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

Mutagenesis Mutagenesis is the process of inducing mutations. Mutations may occur due to exposure to natural mutagens such as ultraviolet (UV) light, to industrial or environmental mutagens such as be... 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

Discontinuous Variation Discontinuous variation is variation within a population of a characteristic that falls into two or more discrete classes. Classic examples include such things as eye color in ... 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

Mutagenesis Mutagenesis is the induction of genetic change in a cell by the alteration of DNA. The change or alteration is heritable in cell progeny and is almost always detrimental. While most mutati... 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

Mutation In general, deoxyribonucleic acid, or DNA, is a very stable molecule. As it conveys genetic information from one generation to the next, errors rarely occur; however, they are not totally abs... 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
458 words, approx. 2 pages
Chemical Mutagenesis The interaction of certain environmental chemical compounds and cell metabolism may result in genetic changes in DNA structure, affecting one or more genes. These chemical-induced... Read more
978 words, approx. 4 pages
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

Genetic Variation Strong paleontological and molecular evidence indicates that life first appeared on Earth about four billions years ago, in the form of prokaryotes, or non-nucleated unicellular orga... 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

Mutations and Mutagenesis 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 ... Read more
758 words, approx. 3 pages
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
588 words, approx. 2 pages
Same-Sense Mutation A same-sense mutation is form of silent mutation where a change in the base sequence of a gene does not result in a change in the amino acid sequence of the protein for which the g... 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

Mutation A mutation is a change in the DNA of an organism, which is genetically transmitted, and may give rise to a heritable variation. Mutagens, substances that have the competence to produce a mu... Read more
