In a typical eukaryotic cell, in which location is DNA found?
A
Cytosolic ribosomes
B
Golgi apparatus lumen
C
Nucleus (as chromosomal DNA)
D
Plasma membrane phospholipid bilayer
Verified step by step guidance1
Recall that in eukaryotic cells, DNA is primarily stored in the nucleus, where it is organized into chromosomes. This is the main site for genetic material storage and regulation.
Understand that cytosolic ribosomes are involved in protein synthesis and do not contain DNA; they translate mRNA into proteins.
Recognize that the Golgi apparatus lumen is a compartment involved in modifying and sorting proteins and lipids, but it does not contain DNA.
Know that the plasma membrane phospholipid bilayer forms the cell's outer boundary and is composed mainly of lipids and proteins, not DNA.
Therefore, the correct location of DNA in a typical eukaryotic cell is the nucleus, where chromosomal DNA is housed.
