Match List-I with List-II
|
List-I (Name of the molecule/drug) |
List-II (Use/disease name) |
|
(A) Thyroxine |
(I) Scurvy |
|
(B) Ascorbic acid |
(II) Thyroid gland |
|
(C) Steroid hormones |
(III) Identification of criminals |
|
(D) DNA fingerprinting |
(IV) Adrenal cortex |
Choose the correct answer from the options given below.
Answer & explanation
Correct answer: option 4
The correct answer is Option (4) → (A)-(II), (B)-(I), (C)-(IV), (D)-(III)
The list pairs biomolecules with where they act or what they are used for. Hormones are matched with the gland that makes them, a vitamin with the deficiency disease it prevents, and a technique with its use.
(A) Thyroxine — This matches (II) Thyroid gland. Thyroxine, an iodinated derivative of the amino acid tyrosine, is the hormone made in the thyroid gland; a low level causes hypothyroidism.
(B) Ascorbic acid — This matches (I) Scurvy. Ascorbic acid is vitamin C; its deficiency causes scurvy (bleeding gums).
(C) Steroid hormones — This matches (IV) Adrenal cortex. Steroid hormones such as glucocorticoids and mineralocorticoids are produced by the adrenal cortex (the sex hormones by the gonads).
(D) DNA fingerprinting — This matches (III) Identification of criminals. The sequence of bases in DNA is unique to each person, so DNA from blood, hair or other traces identifies an individual.
Shortcut: Thyroxine belongs to the thyroid gland, so (A)-(II); only Option (4) has it.
