These extra rings of DNA provided extra genetic information. Name = Found in = Eukaryotic cells Prokaryotic cells Both eukaryotic and prokaryotic cells Neither eukaryotic nor prokaryotic cells

Name = Plasmids

Found in = Prokaryotic cells

Explanation: Plasmids are small, circular pieces of DNA that can replicate independently of chromosomal DNA. They are commonly found in prokaryotic cells, such as bacteria, and can carry genes that provide additional traits, such as antibiotic resistance. Eukaryotic cells can also have extrachromosomal DNA, but it is less common than in prokaryotes.
