Change; alteration, either in form or qualities.
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.
The result of the above process; a suddenly produced variation.
a variant strain of an organism in which the hereditary variant property is caused by a mutation{3}.
The process by which a gene or some other DNA sequence undergoes a permanent change in the structure. Mutations are gene defects where an error in the code for a specific structural or functional protein.
The inherited instructions which determine how all living things, including humans, develop and function are carried in a biological code contained in structures called genes. Errors in this code are called mutations and they may result in diseases in those who inherit them, as in familial CJD.
Changes that occur to the order of bases appearing in the DNA inside a cell.
any chage in the sequence of bases in the DNA molecule resulting in a permanent alteration in some heritable characteristic
An inheritable change in the DNA of an organism. Most commonly this will result in the loss of some specific ability or abilities, for example the ability to form nodules on a particular host.
The alteration of a DNA sequence to produce a different form than the original.
Change in a gene or chromosome resulting in a new trait or characteristic that can be inherited. Mutation can be a source of beneficial genetic variation, or it can be neutral or harmful in effect.
An inherited and spontaneous change in the genetic structure of an organism.
the process or an instance of change or alteration, a genetic change which, when transmitted to offspring gives rise to heritable variations. Muttaqii is the one who is pious and fears Allah Alone. He doesn't fear any idea, anyone or anything else.
A relatively permanent change in hereditary material (gene) involving a physical change in chromosome relations.
Process in which DNA's structure is permanently altered. This may have serious consequences, such as inability to make a normal enzyme for DNA repair with resulting abnormal sensitivity to UV light (as occurs in CS and XP).
A change in the order of the nucleotides that make up DNA. Some mutations can cause disease, others provide healthy variation in a population, and others have no effect.
an abnormality in a gene.
is an alteration of biological inheritance which produces changes in an organism. Inheritance means genetics in our world, but other realms may have other systems. Mutation is very much a random, hit or miss affair. Realistically, most mutations are negative. Deliberately using mutations to create desired changes typically involves inducing millions of mutations and keeping only the few changes that are desired. Even in realms where mutations are more controllable there exists the possibility of extreme negative effects. See Also: Synthesis.

any detectable and heritable change in the genetic material not caused by genetic recombination.
A genetic change of DNA of an individual.
Genetic change caused by natural phenomena or by use of mutagens. Stable mutations in genes are passed on to offspring; unstable mutations are not. From latin word for "change".
a change (usually rare and random) in the base sequence of a DNA molecule.
An inherited change along a very narrow portion of the nucleic acid sequence.
An alteration in genetic structure which is passed from one generation to the next.
A change in the genetic structure, usually spontaneous, that changes the expression of the gene and is transmitted to future generations.
A change in the genetic material (germ plasm) of the organism.
A sudden change in the genetic make-up of a plant, leading to a new feature. This new feature can be inherited. [ GO BACK TO TOP INDEX
Change in the structure of DNA, thus leading to a change in the characterstics of an organism or indivudal cell as a result of altered protein or RNA content specified by the mutated DNA. One can differentiate for example between silent mutations, point mutations, back mutations, or somatic mutations.
The inception of a heritable variation brought about by structural and numerical chromosome changes.
A mutation is any genetic change which is due to malfunction. The genetic machinery is highly reliable, but it is not perfectly reliable. There are many different kinds of misteak that can occur when genetic information is copied. An albino is an example of a person with a mutation. However, many birth defects are not examples of mutation.
Any alteration in the nucleotide sequence (code) of DNA.
An inheritable change in the genetic code.
the process by which a gene or some other DNA sequence undergoes a change in structure. The change in structure may affect the function of the gene and may or may not lead to disease.
in genetics, any change in the amount or chemical structure of the DNA which causes changes in the characteristics of an organism.
A genetic change. When HIV mutates, it can prevent HIV medications from working correctly; when this happens, we say that the HIV has become resistant to that medication.
a minute genetic change to DNA, for example by exposure to hazardous chemicals or copying errors during cell division. If these affect normal cell function it can lead to disease development.
Reproduction with random small changes on the program
A (usually) random change in a structure. In this game, we mutate the control code of the creatures to create diversity (thus driving the evolution), and then let natural selection screen out the best. Essentially this is analogous to the mutation of DNA as happens in biological life.
A sequence variation that deviates from the reference, or "wild type", sequence. This variation can be a SNP, an insertion of sequence, or a deletion of sequence. There can be a great deal of sequence variation between individuals in a population. For example, different humans may have as many as 1 basepair difference every 1000 bp. In practice, mutations are distinguished from variation because they have phenotypic consequences. Mutations in the Pax6 gene that lead to a loss of the function of that gene lead to the eyeless mutation in flies, the Small eye mutation in mice, and aniridia in humans.

any sequence of nucleotides in the copied DNA that does not exactly match with the original sequence of DNA.
The process in which a gene undergoes a permanent, heritable structural change in the DNA or RNA. Mutations can be caused by many factors including environmental insults such as radiation and mutagenic chemicals.
An alteration in the genetic material of a cell caused by change in the sequence of nucleotides in its DNA
a generic change of DNA of an individual.
A permanent change in the hereditary material involving a physical change in chromosomes or genes.
a change in the genetic information within a cell
The source of genetic variation. A change in the wild type (gene) sequence or in the number or structure of chromosomes that may or may not have observable effect or significant impact on health.
A permanent, transmittable change in the characteristics of an offspring that makes it different from its parents.
Any change which alters the identity or order of nucleotide bases within a chromosome.
Variation in reproduction in which the message of heredity (DNA) contained in the genes is imperfectly passed on and from which new species may originate.
an inheritable change resulting from an alteration in DNA.
A change in DNA. Examples of mutations are the insertion or deletion of bases or an alteration of the sequence.
A permanent change, a structural alteration, in the DNA or RNA. Mutations can be caused by many factors including environmental insults such as radiation and mutagenic chemicals. Mutations are sometimes attributed to random chance events.
The random changing of a genotype in moving from one generation to the next. Mutation takes many forms in AgencyGP. They are all examined in the Genetic Engine dialog documentation.
a genetic mishap - usually caused by environmental conditions or a glitch in the replication process, which alters the normal inheritance of a characteristic. For example, some cats that are products of mutations include Scottish Folds (folded ears), Sphinx (hairlessness), Manx (taillessness), Rex (wavy coat), etc.
A sudden genetic change occurring in an organism which can be passed to subsequent generations. (Also called a 'Sport').
An error in the sequence of nucleotides in DNA or RNA that in turn affects the production of proteins. There are two main types of mutations: substitution mutations and frameshift mutations. A substitution mutation occurs when one nucleotide is replaced by another; these mutations can range from ineffectual to drastic, depending on how the new nucleotide changes the protein coded for. Frameshift mutations occur when a nucleotide is either inserted or deleted into the code; these mutations are always drastic and often fatal, since an insertion or deletion will affect every codon in a particular genetic sequence by throwing the entire three-by-three codon frame out of whack.
A heritable change resulting from a permanent alteration in an organism’s DNA sequence.
A permanent genetic change, sometimes resulting in altered structure or function.
A damaged gene that may produce a disease or deficiency.
Genetic change that can occur either randomly or at an accelerated rate through exposure to radiation or certain chemicals (mutagens) and may lead to change in structure of the protein coded by the mutated gene.
Any heritable alteration in the base sequence of the genetic material. See Types of mutations
The process or result of a cellular-level change in a living organism. A good mutation is one that benefits the organism in some way, such as the acquisition of a spare heart, Increased cerebral capacity, or a superhuman ability. A bad mutation is one that impairs the organism in some way, such as a deformity. Many special traits or powers are the result of a body-wide series of good mutations, not just the mutation of single cell.
a random change in the gene pool of a population that gives rise to new alleles and is the source of variation in a population.
any alteration in the DNA sequence.
change in the naturally occurring sequence of a gene
Changes in base composition of DNA. Mutation in sex cells can be inherited.
