Multiple Choice
In eukaryotic cells, DNA can be found in which organelles besides the nucleus?
A
Endoplasmic reticulum and vacuoles
B
Ribosomes and lysosomes
C
Golgi apparatus and peroxisomes
D
Mitochondria and chloroplasts
Verified step by step guidance1
Recall that in eukaryotic cells, DNA is primarily located in the nucleus, which contains the majority of the cell's genetic material.
Understand that besides the nucleus, certain organelles have their own DNA because they originated from ancient symbiotic bacteria; these organelles are mitochondria and chloroplasts.
Recognize that mitochondria contain mitochondrial DNA (mtDNA), which encodes some of the proteins needed for their function, especially related to energy production.
Know that chloroplasts, found in plant cells and some protists, also contain their own DNA, which is involved in photosynthesis and other chloroplast-specific functions.
Eliminate other organelles such as the endoplasmic reticulum, vacuoles, ribosomes, lysosomes, Golgi apparatus, and peroxisomes, as they do not contain DNA.
