Scelta multipla
In a typical eukaryotic cell, where is most DNA found?
A
In the Golgi apparatus within secretory vesicles
B
In the nucleus, packaged as chromatin
C
In the rough endoplasmic reticulum attached to ribosomes
D
In the cytosol as free circular DNA molecules
Guida verificata passo dopo passo1
Recall the main organelles in a eukaryotic cell and their functions, focusing on where genetic material is typically located.
Understand that DNA in eukaryotic cells is primarily stored in the nucleus, where it is organized into chromatin, a complex of DNA and proteins.
Recognize that the Golgi apparatus is involved in modifying and packaging proteins and lipids, not storing DNA.
Know that the rough endoplasmic reticulum is associated with protein synthesis due to ribosomes but does not contain DNA.
Remember that free circular DNA molecules are characteristic of prokaryotic cells or mitochondria, not the cytosol of typical eukaryotic cells.
