Si un RNA mensajero (mRNA) esta formado por 700 nucleótidos, ¿puede ser posible que
alexgriva [62]

Answer:

Si, esto es posible ya que para llegar a su forma madura el ARN mensajero sufre un procesamiento conocido como empalme alternativo donde su longitud se reduce drásticamente mediante la eliminación de regiones no codificantes (intrones) presentes en el trascripto primario

Explanation:

En células eucariotas, la transcripción refiere al proceso donde un gen es usado como templado para generar un ARN mensajero (ARNm) inmaduro conocido como pre-ARNm, el cual contiene regiones cortas codificantes (exones) y regiones largas no codificantes (intrones). Durante el proceso de empalme alternativo, también conocido como <em>splicing</em> alternativo, este pre-ARNm sufre un procesamiento mediante el cual los intrones son eliminados y los exones son retenidos y empalmados, con lo cual el ARNm maduro final reduce drásticamente su longitud original. En el caso arriba descripto, una proteína con 70 aminoácidos resultaría de la traducción de un ARNm maduro que posee 210 bases nucloetídicas, ya que cada triplete de nucleótidos o 'codón' corresponde a un sólo aminoácido agregado a la cadena polipeptídica durante la síntesis proteica en los ribosomas.
