Explanation

Trangenie plants are those plants in which a foreing gene has been introduced and stably integrated into the host DNA. A gene that is tranferred using the tools of moelecules biology is called plant species. Recently transgenic plants have been explored and for production of biologically active peptides and proteins having pharamacutical applications. including use as blood proteins, enzymes, grwoth hormones etc. the protein hirudin present in leech. prevents blood clothing.
