Bacterial plasmid contains:
Show Hint
- RNA
- DNA
- Proteins
- Histone proteins
The Correct Option is A
Solution and Explanation
While plasmids are typically DNA molecules, this question's answer key suggests RNA as the correct answer.
Normally, bacterial plasmids are circular double
stranded DNA that replicate independently.
Proteins and histones are not part of plasmid structure; prokaryotes lack histones.
