Answer:
The active functional group of a drug is that one that has the most prominent quality of adherence to the corresponding group on the target site and this selective binding of the group gave the property of targeted therapy and action. The pharmacophore modelling is done to ensure the design success of a drug but real life circumstances are mostly unpredictable. By this specific targeted action a drug acquires the property of differentiating between healthy and infected cells. Infected cells always have something different in their functional group expression as compare the the healthy cells. This helps the drug to differentiate between them.
Answer: b. DNA
Explanation:
DNA is a genetic material commonly found in all living beings. It is present in a thread like structure that is called as the chromosome. The DNA is double helical structure which exhibits the segments of small units called as the genes. The gene is a hereditary material which encodes for a particular protein. Each gene is responsible for determining a particular trait in living beings.

Explanation:
Stenting is an alternative to endarterectomy for treatment of carotid artery stenosis, but long-term efficacy is uncertain.
What is Stenting?
A stent is a small tube made of wire mesh. It holds open an artery and stays there indefinitely.
If a coronary artery (a blood vessel that supplies an accumulation narrows the heart muscle. Plaque is a fatty buildup that can lessen the blood flow. if there is less blood flow Chest pain may be caused by damage to the heart muscle.If a clot develops and entirely obstructs the a portion of the heart muscle's blood flowthe heart attack happens.Stents maintain coronary artery patency.and lower the risk of having a heart attack.
A stent is deployed by collapsing it and placing it over the
the balloon catheter. It is then brought close to the obstruction.

Answer: B. Sarcoplasmic reticulum
Explanation: The sarcoplasmic reticulum is the name given to the organelle in the muscle cell, in charge of the storage and regulation of the intracellular calcium levels. It is the smooth endoplasmic reticulum in muscle cells, it means that it does not have ribosomes in its surface.
Option A. Incorrect. A SARCOMERE is the functional and anatomic unit of the striated muscle (skeletal muscle and heart muscle). This word comes from the greek: <em>sarkos (meat), meros (part). </em>That is reason you could find other structures of the muscle cell with this root (SARCO...).
Option C. Incorrect. "Arcolemma" this word does not exist. But if it refers to SARCOLEMMA, this word means: <em>sarko (meat), lema (cortex) </em>in greek<em>. </em>It is the plasma membrane of the muscle cells.
Option D. Incorrect. The SARCOPLASM, comes from the greek: <em>sarko (meat), plasm (matter). </em>This structure is the citoplasm of the muscle cells.
In conclusion, the word SARCOPLASMIC RETICULUM, refers to a <em>structure of the muscle cell, </em>that in this case, is the RETICULUM or the SMOOTH ER.
