Answer:

Adenina (30%), citosina (15%), guanina (15%) o timina (40%)

Explicación:

El 30% de las bases nitrogenadas totales lo ocupa la adenina, el 15% de las bases nitrogenadas totales corresponde a la citosina, el 15% de las bases nitrogenadas totales toma la guanina y el 40% restante de las bases nitrogenadas totales lo ocupa la timina. Entonces, al combinar todos estos porcentajes, obtenemos el 100 por ciento del volumen del ácido desoxirribonucleico (ADN).

<h2>Messenger RNA</h2>

Explanation:

  • Messenger RNA (mRNA) is a solitary stranded RNA atom that relates to the hereditary arrangement of a quality and is read  by the ribosome during the time spent creating a protein
  • The three most significant strides of pre-mRNA processing are the expansion of settling and <em>signaling factors at the 5′ and 3′  ends of the molecule,</em> and the expulsion of mediating arrangements that don't indicate the <em>proper amino acids. </em>the mRNA <em>transcript can be “edited”</em>  after it is transcribed.
  • During transcription the RNA polymerase read the layout DNA strand the <em>3′→5′ way, however the mRNA is shaped in the 5′ to 3′  direction. </em>
  • The essential capacity of mRNA is to go about as a intermediary between the <em>hereditary data in DNA</em> and the amino acid sequence of proteins.
