Which is not present in bacteria?
Correct answer: C. Histones
- A. Peptidoglycan
- B. rRNA
- C. Histones
- D. Teichoic acid
Explanation
In general, bacteria do not contain histones. Histones are a class of proteins that play a crucial role in the packaging and organization of DNA in eukaryotic cells, such as those found in plants, animals, and fungi. Histones help condense the long, linear DNA strands into a compact and organized structure known as chromatin, which is essential for regulating gene expression and DNA replication.
