Descriptor sondas de ARN
Entry term(s) sonda de ARN
sondas de ARN de genes
Scope note: ARN que suele producirse por transcripción de ADN clonado, el cual es complementario de un ARNm o ADN específico y que se usa generalmente en el estudio de genes víricos, de la distribución de ARN específico en tejidos y células, la integración del ADN vírico en genomas, la transcripción, etcétera. Aunque es preferible usar las SONDAS DE ADN en un nivel más macroscópico para detectar la presencia de ADN/ARN de especies o subespecies específicas, en los estudios genéticos se prefieren las sondas de ARN. Las sondas suelen marcarse con los radioisótopos 32P y 125I, y con el marcador químico biotina. Las sondas de ARN pueden dividirse por categorías en sondas ARN de sentido +, sondas ARN de sentido - y sondas de ARN antisentido.

Scope note: RNA, usually prepared by transcription from cloned DNA, which complements a specific mRNA or DNA and is generally used for studies of virus genes, distribution of specific RNA in tissues and cells, integration of viral DNA into genomes, transcription, etc. Whereas DNA PROBES are preferred for use at a more macroscopic level for detection of the presence of DNA/RNA from specific species or subspecies, RNA probes are preferred for genetic studies. Conventional labels for the RNA probe include radioisotope labels 32P and 125I and the chemical label biotin. RNA probes may be further divided by category into plus-sense RNA probes, minus-sense RNA probes, and antisense RNA probes.
