Carbon is the only element that can form so many different compounds because each carbon atom can form four chemical bonds to other atoms, and because the carbon atom is just the right, small size to fit in comfortably as parts of very large molecules. ... They can even join "head-to-tail" to make rings of carbon atoms.
RFLP, AmpFLP are the two techniques which is used to create DNA profile
Explanation:
<u>RFLP technique: </u> RFLP technique stands for “Restriction Fragment Length Polymorphism”. It is molecular method of genetic analysis which allows to identified based unique pattern of restriction enzyme where DNA is cutting in specific regions. It requires large amount of sample. The costing is very high
<u>AmpFLP: </u>The AmpFLP stands for amplified length polymorphism. It is PCR based tool. Firstly, it uses as restricted enzyme. It is cheaper than RFLP technique. It is used as genetic engineering
Qualitative analytic methods are needed to determine THE IDENTITY OF THE POISON USED IN A MURDER.
Quantitative analytic methods are used to identify unknown materials such as chemical compounds, poisons, etc. In a criminal investigation case, qualitative analytic method can be used to identify the particular poison that was used to murder a victim. Qualitative methods do not involve numeric data or figures while quantitative methods typically has to do with the quantity of a substance that is involved in a particular situation.This is basic difference between the two methods.
Answer:
Aspirin works by inhibiting the production of prostaglandins. Aspirin inhibits the formation of prostaglandins by combining with the COX enzymes. Prostaglandins function as messenger molecules to monitor different physiological procedures in distinct regions of the body. One of the prime activities of prostaglandins is to stimulate inflammation and pain.
Prostaglandins are also the essential controller of platelet aggregation. By changing the COX enzymes inside the platelets, aspirin makes platelets to lose the stickiness, which is required to instigate clotting of blood.
There are two forms of cyclooxygenase, that is, COX-1 and COX-2. COX-1 generates prostaglandins and COX-2 mediates pain and swelling in response to tissue injury. Aspirin prevents both COX-1 and COX-2 functioning, while COX-2 is the therapeutic target of the drug.
However, it is the association of aspirin with COX-1 in the gastrointestinal tract, which results in the unwanted side effects of the drug. COX-1 is required to sustain a thick lining of the stomach. As aspirin inhibits the COX-1 enzyme, thus, the continuous use of the drug can result in the thinning of mucus, which safeguards the stomach from gastric juices.
In such cases, stomach bleeding, ulcers, and in certain situations perforation of the stomach can take place. Therefore, aspirin exhibits both bad and good effects.
