Which of the following organelles is responsible for housing the genetic material in a eukaryotic cell?
A
Golgi apparatus
B
Endoplasmic reticulum
C
Nucleus
D
Mitochondrion
Verified step by step guidance1
Understand the role of organelles in a eukaryotic cell. Organelles are specialized structures within cells that perform distinct functions. The nucleus is one such organelle responsible for housing genetic material.
Recall that genetic material in eukaryotic cells is stored in the form of DNA (deoxyribonucleic acid), which contains instructions for cellular functions and replication.
Identify the nucleus as the organelle that contains chromatin, which is composed of DNA and proteins. The nucleus is surrounded by a double membrane called the nuclear envelope, which protects the genetic material and regulates the exchange of substances between the nucleus and cytoplasm.
Differentiate the nucleus from other organelles listed in the problem: the Golgi apparatus (involved in packaging and transport), the endoplasmic reticulum (involved in protein and lipid synthesis), and the mitochondrion (responsible for energy production). None of these organelles house genetic material.
Conclude that the nucleus is the correct answer because it is the organelle responsible for storing and protecting the genetic material in eukaryotic cells.
