DEFINITION

A selective increase in the number of copies of a gene coding for a specific protein without a proportional increase in other genes. It occurs naturally via the excision of a copy of the repeating sequence from the chromosome and its extrachromosomal replication in a plasmid, or via the production of an RNA transcript of the entire repeating sequence of ribosomal RNA followed by the reverse transcription of the molecule to produce an additional copy of the original DNA sequence.
Aumento selectivo del número de copias de un gen que codifica una proteína específica sin un aumento proporcional en los otros genes. Se produce en forma natural mediante la extensión de una copia de la secuencia que se repite desde el cromosoma y su replicación extracromosómica es un plasmido, o mediante la producción de una transcripción de ARN de toda la secuencia que se repite de ARN ribosomático, seguido de transcripción inversa de la molécula para producir una copia adicional de la secuencia original de ADN.
