vitfil [10]

Answer:

The water soluble hormones affect the target cells with least amount of interaction.

Explanation:

Hormones are the chemical messengers. These are the substances secreted by the endocrine glands. The hormones are secreted directly into the bloodstream and are carried to the target cells within the blood only.  

Based on their structure, hormones are water-soluble or lipid-soluble. The lipid-soluble hormones are steroid hormones and thyroid hormones. These hormones can easily pass through the lipid bilayer of the cell membrane of the target cell. Therefore, the lipid-soluble hormones have intracellular receptors that are present in either cytoplasm or the nucleus of the target cells.  

On the other hand, the water-soluble hormones can not pass through the lipid bilayer of the target cells. Therefore, these hormones have extracellular receptors on the surface of the target cells. Binding of the water-soluble hormones to their cell surface receptors triggers the production of the intracellular second messengers that finally carry the signal to the target protein or any other target molecule.

<u>Therefore, a water-soluble hormone exhibits the least amount of interaction with the target cell. Amine hormones such as epinephrine and melatonin, peptide hormones such as oxytocin are some examples of the water-soluble hormones.  </u>

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.
