Multiple Choice
In eukaryotic cell architecture, what organelle is considered the control center of the cell because it houses most of the genetic material and regulates gene expression?
A
Mitochondrion
B
Nucleus
C
Golgi apparatus
D
Ribosome
Verified step by step guidance1
Understand the role of each organelle listed: Mitochondrion, Nucleus, Golgi apparatus, and Ribosome.
Recall that the organelle responsible for housing most of the genetic material (DNA) in eukaryotic cells is the nucleus.
Recognize that the nucleus controls gene expression by regulating which genes are turned on or off, thus acting as the control center of the cell.
Note that mitochondria are primarily involved in energy production, Golgi apparatus in protein modification and sorting, and ribosomes in protein synthesis, so they do not serve as the control center.
Conclude that the nucleus is the organelle considered the control center of the cell because it contains the genetic material and regulates gene expression.
