DNA is found in the nucleus of the cell, which is responsible for controlling cell activities and reproduction. The rough endoplasmic reticulum contains ribosomes, the sites of protein synthesis. Correct answer: IV. Nucleus.
Deoxyribonucleic acid (DNA) can be found in the nucleus of the cell. The nucleus is the organelle that contains the genetic material of the cell and is responsible for controlling the cell's activities and reproduction.
The rough endoplasmic reticulum (ER) is also involved in protein synthesis and is studded with ribosomes. These ribosomes are the sites where proteins are synthesized, contributing to various cellular functions.
Therefore, the correct answer to the question is IV. Nucleus, as DNA is primarily housed in the nucleus of eukaryotic cells.
