B

a toxic molecule isotated from Gossypium hirsutum which reduces human fertility

Text Solution

Verified by Experts

The correct Answer is:
c
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. The gene was chemically synthesized and introduced in Brassoica napas and later on the seeds contained the protein.
