What are plasnids?

Plasmids are small, circular DNA molecules found in bacteria and some eukaryotic cells that replicate independently of chromosomal DNA. They often carry genes that provide advantageous traits, such as antibiotic resistance or metabolic capabilities. Plasmids are commonly used in genetic engineering and biotechnology as vectors to transfer genes between organisms. Their ability to easily replicate and exchange genetic material makes them important tools in molecular Biology research.
