mutation mutation. n. 1. (Genetics) the act or process of mutating; change; alteration. 2. a change or alteration. 3. (Genetics) a change in the chromosomes or genes of a cell. When this change occurs in the gametes the structure and development of the resultant offspring may be affected. See also inversion 11.

Mutation In biology, a mutation is a permanent change of the nucleotide sequence of the genome of an organism, virus, or extrachromosomal DNA or other genetic elements.utations in the structure of genes can be classified as: , 1  such as those affecting a small gene in one or a few nucleotides, including: 2  Point mutations, often caused by chemicals or malfunction of DNA replication, exchange a single nucleotide for another. 3  These changes are classified as transitions or transversions.

Mutations A mutation is a heritable change in DNA. A mutation may lead to a change in the amino-acid sequence of a protein, possibly affecting its function. A point mutation affects a single base pair.

-   Answer   A mutation is any change to a strand of DNA which is passed on to an organism's offspring.      DNA mutations are caused usually by chemical in … teractions or radiation (natural and manmade), and most are harmless.onfidence votes 263K. DNA mutation affects the mRna as it is the genetic profile for the being. In replication, the mutation is also replicated propagating the change in all newly developed cells.

Mutations Mutation [ edit | edit source]. It is defined as a change in the DNA sequence of a cell's genome. Mutations can be divided into 3 classes or categories: 1  Genome mutations: Mutations that affect the number of chromosomes. 2  Chromosome mutations: Mutations that alter the structure of individual chromosomes. 3  Also known as Gross mutations.

Definitions &Translations mutation(n.) (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.

What is a gene mutation and how do mutations occur? A gene 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.Mutations range in size; they can affect anywhere from a single DNA building block (base pair) to a large segment of a chromosome that includes multiple genes.e novo mutations may explain genetic disorders in which an affected child has a mutation in every cell in the body but the parents do not, and there is no family history of the disorder.

Effects of Mutations on Protein Function: Missense, Nonsense, and Silent Mutations But, the truth is that most mutations are not that extreme. In biology, a mutation is any change in the nucleotide sequence of DNA. Some mutations affect large sections of DNA, and others only affect certain points along the DNA strand. These small, specific mutations are called point mutations.

Mutation In biology, a mutation is a permanent change of the nucleotide sequence of the genome of an organism, virus, or extrachromosomal DNA or other genetic elements.utations result from damage to DNA which is not repaired, 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 discernible changes in the observable characteristics (phenotype) of an organism.

mutation A change in the genes or chromosomes of an organism. Mutations occurring in the reproductive cells, such as an egg or sperm, can be passed from one generation to the next. Most mutations have harmful effects, but some can increase an organism's ability to survive.. Change in a gene or genes of a living cell. A mutation in some way changes the cell’s characteristics and will be inherited. See chromosome, genes.
