The 'Hormone Prolactin' is secreted by the anterior pituitary gland. Its primary physiological role is to: MCQ with Answer and Explanation

The 'Hormone Prolactin' is secreted by the anterior pituitary gland. Its primary physiological role is to:
A. Trigger ovulation
B. Maintain the corpus luteum
C. Stimulate the development of mammary glands and the production of milk (lactogenesis)
D. Stimulate uterine contractions
Answer: Option C
Solution (By JKSSB Mock Tests)
Prolactin (PRL) is a peptide hormone secreted by the lactotroph cells of the anterior pituitary gland. Its primary and namesake function is to stimulate the development of the mammary glands during pregnancy and to initiate and maintain the production of milk (lactogenesis) after childbirth. While prolactin levels rise significantly during pregnancy, the high levels of estrogen and progesterone inhibit actual milk secretion until after delivery. Suckling by the infant is the primary stimulus for continued prolactin release.

Question #1
Which plant hormone is primarily responsible for apical dominance?
A. Auxin
B. Gibberellin
C. Cytokinin
D. Ethylene

Correct Answer: Option A


Explanation:
Auxin (indole-3-acetic acid) produced at the shoot apex suppresses the growth of lateral buds, a phenomenon called apical dominance. Removing the apex allows lateral buds to grow. Cytokinin promotes cell division and counteracts apical dominance. Gibberellin stimulates stem elongation, and ethylene is involved in fruit ripening and senescence. The auxin-cytokinin ratio determines root and shoot differentiation in tissue culture.

Question #2
The scientist who discovered that DNA is the genetic material in bacteriophages was:
A. Meselson and Stahl
B. Hershey and Chase
C. Watson and Crick
D. Avery, MacLeod, McCarty

Correct Answer: Option B


Explanation:
Hershey and Chase (1952) used radioactive isotopes (³²P and ³⁵S) to show that DNA, not protein, enters bacteria during T2 phage infection and is the genetic material. Avery et al. earlier showed transforming principle was DNA. Watson and Crick determined structure, Meselson-Stahl replication mode.

Question #3
Which of the following is a biopesticide?
A. DDT
B. Malathion
C. Lindane
D. Bacillus thuringiensis

Correct Answer: Option D


Explanation:
Bacillus thuringiensis (Bt) is a bacterium producing crystal (Cry) proteins toxic to specific insect larvae, used as a biological insecticide. DDT, malathion, and lindane are synthetic chemical pesticides. Biopesticides are eco-friendly, target-specific, and biodegradable. Bt formulations are used in organic farming. The cry gene is also used in GM crops like Bt cotton.
