Explanation

Plasmids are important vectors in modern genetic engineering. A plasmid is a small, circular DNA molecule that can raplicate independently within a bacterial cell. Scientists often use plasmids to introduce foreign DNA bacterial cells for various purposes, such as producing recombinant proteins, studying gene function and creating genetically modified organisms. Plasmids can be engineered to carry specific genes of interest and then transferred into host cells, allowing for the expression of those genes.
