Plasmid
Plasmid explained in an easy to understand way:
Imagine you're trying to get through a busy day, juggling multiple tasks at work, but you also have a personal project that you're passionate about and work on during breaks. This personal project is like a plasmid, a small ring of DNA within a bacterial cell that operates independently, just as your project runs alongside your main job responsibilities. Much like how your project doesn't interfere with your job but can still progress independently, a plasmid can replicate on its own without relying on the main cellular processes linked to the chromosomes, allowing it to thrive in its own right.
