How bacteria take up plasmid during the process of recombinant DNA technology ?

Explanation

### Step-by-Step Solution:

1. **Understanding Plasmids**:
- Plasmids are small, circular pieces of DNA that exist independently of chromosomal DNA in bacteria. They can replicate independently and are often used as vectors in recombinant DNA technology to carry foreign DNA into a host cell.

2. **Preparation of Recombinant DNA**:
- The desired DNA fragment is ligated (joined) to the plasmid DNA, creating recombinant DNA (rDNA). This rDNA is what we aim to introduce into bacterial cells.
