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:
An experiment
Explanation:
The answer is an experiment
Answer:
Basically, in nature, the community in an ecosystem is shaped by the environmental factors, and ecological succession occurs when these environment factors are modified. Microbes are the main decomposers of organic materials, and changes in microbial community are often associated with functional capabilities.
Explanation:
Drugs that selectively stimulate the contraction of the myocardium are known as oxytocic agents.
<h3>
What is myocardium?</h3>
The myocardium is the middle layer of the heart. It is the thickest layer between the single-layer endocardium and the outer epicardium. The myocardium is composed of cardiomyocytes.
The function of the myocardium is to facilitate the contraction and relaxation of the heart walls. It helps in the conduction of electrical stimuli.
Cardiac muscles are under to stimulate digoxin, dopamine. Cardiostimulatoy drug stimulate and enhances cardiac function increasing heart rate. Hypertension, Angina, myocardial infraction, and heart failure are some of the disorders related to the heart.
Therefore, Drugs that selectively stimulate the contraction of the myocardium are known as oxytocic agents.

“Pascal’s principle (also known as Pascal’s law) states that when a change in pressure is applied to an enclosed fluid, it is transmitted undiminished to all portions of the fluid and to the walls of its container. In an enclosed fluid, since atoms of the fluid are free to move about, they transmit pressure to all parts of the fluid and to the walls of the container. Any change in pressure is transmitted undiminished.”
