Anatomy & Physiology Question #9

Question

The nurse is reviewing the structure of a cell. In which of these organelles is chromatin found?

Answers

1. Nucleus
2. Rough endoplasmic reticulum
3. Smooth ER or endoplasmic reticulum
4. Lysosomes in the ER

Explanation

The correct answer is A. The nucleus is an organelle, an intracellular membrane-enclosed compartment with a specific function. The nucleus also contains chromatin. Chromatin is a complex of DNA and proteins. The endoplasmic reticulum is not designed to hold or function in the DNA synthesis process and would be incorrect.
