The process of RNA editing is the alteration of the sequence of nucleotides in the RNA after it has been transcribed from DNA, but before it is translated into a protein. RNA editing occurs by two distinct mechanisms:<em><u /><u>Substitution</u> <u>editing </u></em>and <u><em>Insertion/</em></u><em></em><u><em>deletion</em></u><em> <u>editing</u></em>.
<u><em>Substitution editing</em></u> is the chemical alteration of individual nucleotides. These alterations are catalyzed by enzymes that recognize a specific target sequence of nucleotides:
*Cytidine Deaminases that convert a C in the RNA to uracil.
*<em />adenosine deaminases that convert an A to inosine,which the ribosome translates as a G.<span>Thus a CAG codon</span><span> (for Gln) can be converted to a CGG codon (for Arg).
<em><u>*Insertion/deletion editing</u></em><em><u /></em><u /> is the insertion or deletion of nucleotides in an RNA.
These alterations are mediated by guide RNA molecules that base-pair as best they can with the RNA to be edited and serve as a template for the addition( or removal) in the target.</span>
Answer:
La vejiga natatoria en un pez, se ve afectada por la presión hidrostatica del agua, generando presión y estrechamiento sobre esta, al disminuirse hace más fácil la inmersión, puesto que está vejiga contiene aire que tiene peso menor que el agua y hace flotar con más facilidad al pez, sin embargo cuando el pez sube, la vejiga aumentará su volumen y tendrá que nadar más para mantenerse más abajo en el agua
The answer is A. This ensures that the resource has enough time to regenerate so as to sustain consumption. An example is that of the carrying capacity of a habitat. If a herd of cows exceed the carrying capacity of the grazeland, the grass will be depleted and the area will be predisposed to desertification. The environment will not be able to sustain the cows anymore until the herd number reduce.
