Which of the following pairs of cell organelles contains DNA?

Exercise: Revise, Reflect, Refine | Q: 7
For More Understanding

Explanation

Option (ii) is correct because the provided text explicitly states that the nucleus contains chromosomes, which are composed of DNA and carry genetic information. Among the given options, only (ii) Mitochondria, Nucleus and (iv) Nucleus, Lysosomes include the nucleus. Since lysosomes do not contain DNA and mitochondria are known to contain their own DNA, option (ii) forms the correct pair. The other organelles listed in options (i) and (iii), such as ribosomes and Golgi bodies, do not contain DNA.

Solution Steps

  1. Step 1: Identify from the context that the nucleus contains chromosomes composed of DNA.

  2. Step 2: Eliminate options (i) and (iii) because they list organelles (ribosomes, Golgi bodies) that do not contain DNA.

  3. Step 3: Compare options (ii) and (iv). Both contain the nucleus, but option (ii) pairs it with mitochondria (which contains DNA), whereas option (iv) pairs it with lysosomes (which do not contain DNA).

  4. Step 4: Conclude that option (ii) is the correct pair of cell organelles containing DNA.
