Una mutación es el cambio al azar en la secuencia de nucleótidos o en la organización del ADN ( genotipo) o ARN de un ser vivo 1 que produce una variación en las características de este y que no necesariamente se transmite a la descendencia. Se presenta de manera espontánea y súbita o por la acción de mutágenos.
Hace 2 días · Mutation, an alteration in the genetic material (the genome) of a cell of a living organism or of a virus that is more or less permanent and that can be transmitted to the cell’s or the virus’s descendants. The genomes of organisms are all composed of DNA, whereas viral genomes can be of DNA or RNA.
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.
Las mutaciones son cambios en la información contenida en el material genético. Para la mayoría de seres vivos, esto significa un cambio en la secuencia del ADN, el material hereditario de la vida. Por lo tanto, un cambio en el ADN de un organismo puede producir cambios en todos los aspectos de su vida.
Hace 2 días · A mutation is a change in the DNA sequence of an organism. Mutations can result from errors in DNA replication during cell division, exposure to mutagens or a viral infection. Germline mutations (that occur in eggs and sperm) can be passed on to offspring, while somatic mutations (that occur in body cells) are not passed on.
A mutation is a heritable change in the nucleotide sequence of an organism's DNA that ultimately serves as a source of genetic diversity. A single base change can...
A mutation is a change in a genetic sequence. Mutations include changes as small as the substitution of a single DNA building block, or nucleotide base, with another nucleotide base.
