Definition

A small, circular piece of DNA that can replicate independently inside a cell, often found in bacteria and used in genetic research to move genes between cells.

Example

Scientists use plasmids to insert new genes into bacteria for research purposes.

Conversation

Have you heard about the role of a plasmid in genetic engineering?

Yeah, I think it's a small circle of DNA that helps transfer genes, right?

Exactly! Scientists use plasmids to modify bacteria for research purposes.

That's pretty cool! I didn't realize how important they are in biotechnology.

Root Explanation

**Plasmid** → It is formed from "plasma" (from Greek *plasma*, meaning something molded or formed) and the suffix "-id" (meaning related to or connected with). The word "plasmid" refers to a genetic structure that is related to or derived from the plasma of a cell, often existing independently of chromosomal DNA.

Memory Tip

Think of 'plasma' as something that is 'molded' or 'formed' in a cell, and the '-id' indicates it is related to that plasma. This helps you remember that a plasmid is a genetic structure connected to the cell's plasma.
