Question

Where can extrachromosomal DNA be found in eukaryotes? Please select all that apply.
A) Chloroplasts
B) Plasmids
C) Mitochondria
D) Ribosomes

Chloroplasts and mitochondria both contain their own small genomes. They likely derived from prokaryotes that were engulfed by eukaryotic cells early in evolutionary development. Some unicellular eukaryotes contain plasmids. Ribosomes are partly comprised of ribosomal RNA, but do not contain DNA.
