Choose the correct answer from the options given below:
Answer & explanation
Correct answer: option 2
The correct answer is Option (2) → (A) - (IV), (B) - (III), (C) - (II), (D) - (I)
(A) Trichoderma polysporum — this matches (IV). Cyclosporin A. This fungus produces cyclosporin A, which suppresses the immune system. It is given to organ-transplant patients so that the body does not reject the new organ.
(B) Streptococcus — this matches (III). Clot buster to remove blood clots. The bacterium Streptococcus produces streptokinase, which, modified by genetic engineering, dissolves blood clots in patients after a heart attack.
(C) Aspergillus niger — this matches (II). Citric acid. This fungus is used in industry to produce the organic acid citric acid.
(D) Monascus purpureus — this matches (I). Blood cholesterol lowering agent. This yeast produces statins, which block the enzyme that makes cholesterol and so lower blood cholesterol.
