NEET 2019 · BiologyEndomembranePrevious Year Question
Which of the following pair of organelles does not contain DNA?
Answer: (C) Lysosomes and Vacuoles. Answer: (C) Lysosomes and Vacuoles Solution: Lysosomes (hydrolytic enzyme vesicles) and vacuoles (membrane-bound spaces storing water, sap and waste) do not contain DNA.
- A.Mitochondria and Lysosomes
- B.Chloroplast and Vacuoles
- C.Lysosomes and Vacuoles✓
- D.Nuclear envelope and Mitochondria
Correct Answer
(C) Lysosomes and Vacuoles
Solution & Explanation
Answer: (C) Lysosomes and Vacuoles Solution: Lysosomes (hydrolytic enzyme vesicles) and vacuoles (membrane-bound spaces storing water, sap and waste) do not contain DNA. In contrast, mitochondria and chloroplasts possess their own circular DNA, and the nucleus (bounded by the nuclear envelope) contains the chromosomal DNA. Thus the only pair lacking DNA is lysosomes and vacuoles. NCERT Reference: Ch 8, p.97, lines 13-14: "possesses single circular DNA molecule, a few RNA molecules, ribosomes"

BiolGiven below are two statements: One is labelled as Assertion (A) and the other is labelled as Reason (R). Assertion (A): The primary function of the Golgi apparatus is to package the materials made by the endoplasmic reticulum and deliver it to intracellular targets and outside the cell. Reason (R): Vesicles containing materials made by the endoplasmic reticulum fuse with the cis face of the Golgi apparatus, and they are modified and released from the trans face of the Golgi apparatus. In the light of the above statements, choose the correct answer from the options given below:BiolChoose the correct statements regarding cell organelles and their inclusions. A.
