ARN Ribosómico

Spanish from Spain

Descriptor	ARN ribosómico
Entry term(s)	RNA ribosómico RNAr
Scope note:	Es la forma más abundante de ARN; junto con las proteínas, constituye los ribosomas, desempeñando un papel estructural e interviniendo en la unión ribosómica del ARNm y los ARNt. Las cadenas se designan convencionalmente por sus coeficientes de sedimentación. En los eucariotas existen cuatro cadenas grandes, que se sintetizan en el nucléolo y constituyen aproximadamente el 50 por ciento del ribosoma. (Dorland, 28th ed)

Scope note:

The most abundant form of RNA. Together with proteins, it forms the ribosomes, playing a structural role and also a role in ribosomal binding of mRNA and tRNAs. Individual chains are conventionally designated by their sedimentation coefficients. In eukaryotes, four large chains exist, synthesized in the nucleolus and constituting about 50% of the ribosome. (Dorland, 28th ed)
