In eukaryotic cell architecture, which organelle is commonly described as the control center of the cell because it houses most of the genetic material and regulates gene expression?
A
Golgi apparatus
B
Lysosome
C
Mitochondrion
D
Nucleus
Verified step by step guidance1
Identify the organelle responsible for housing the cell's genetic material, which is DNA. This organelle contains the chromosomes that carry genes.
Understand that the organelle which regulates gene expression controls which genes are turned on or off, influencing cell function and activity.
Recall that the Golgi apparatus is involved in modifying, sorting, and packaging proteins, not in housing genetic material.
Recognize that lysosomes are involved in digestion and waste removal, not in gene regulation or housing DNA.
Conclude that the nucleus is the organelle that contains most of the genetic material and acts as the control center by regulating gene expression.
