Question

Which of the following product of r - DNA is used to dissolve blood clots :

• A. Erythropoetin
• B. Interferon
• C. Tissue plasminogen activator
• D. Interleukins

Answer 1

The correct option is C Tissue plasminogen activator

Tissue plasminogen activator is a protein involved in the breakdown of blood clots. It is a serine protease found on endothelial cells, the cells that line the blood vessels. As an enzyme, it catalyzes the conversion of plasminogen to plasmin, the major enzyme responsible for clot breakdown. They dissolve blood clots after heart attacks and strokes.

Erythropoietin helps in stimulation of the formation of erythrocytes $\text{(RBCs})$ for patients suffering from anaemia during dialysis or side effects of $\text{AIDS}$ patients treated by drugs.

Interferon is used in treatment of pathogenic viral infections, cancer. Interleukin is used in enhancement of action of immune system.

So, product of r - $\text{DNA}$ used to dissolving blood clots is tissue plasminogen activator.
