In eukaryotic cell architecture, which organelle is considered the cell's control center because it houses most of the genetic material and regulates gene expression?
A
Nucleus
B
Mitochondrion
C
Golgi apparatus
D
Ribosome
검증된 단계별 안내1
Understand the role of each organelle listed: the nucleus, mitochondrion, Golgi apparatus, and ribosome.
Recall that the nucleus contains the majority of the cell's DNA, which holds the genetic instructions necessary for cell function.
Recognize that the nucleus regulates gene expression by controlling which genes are turned on or off, thus directing cellular activities.
Compare this with other organelles: mitochondria generate energy, Golgi apparatus modifies and packages proteins, and ribosomes synthesize proteins but do not control genetic information.
Conclude that the organelle acting as the cell's control center by housing genetic material and regulating gene expression is the nucleus.
