JNTU B.Pharmacy III CELL AND MOLECULAR BIOLOGY Previous Question Paper (July/August - 2023 - R17)
Answer all questions from Part A. Answer any one question from each unit in Part B.
Part A
Define molecular biology.
Answer
Molecular biology is the branch of biology that deals with the structure, function, and interactions of cellular molecules—specifically nucleic acids (DNA and RNA) and proteins—that carry out the biological processes essential for life.
What are organic compounds and what are the functional groups?
Answer
Organic compounds are chemical compounds primarily composed of carbon atoms covalently bonded to hydrogen, and often oxygen, nitrogen, or other elements. Functional groups are specific clusters of atoms within molecules that are responsible for the characteristic chemical reactions of those molecules, such as hydroxyl (-OH), carboxyl (-COOH), amino (-NH2), and phosphate (-PO4) groups.
