Answer 1

Answer: (B)

A plasmid that contains foreign DNA

Chimera, in genetics, an organism or tissue that contains at least two different sets of DNA, most often originating from the fusion of as many different zygotes (fertilized eggs). The term is derived from the Chimera of Greek mythology, a fire-breathing monster that was part lion, part goat, and part dragon. In the options given above a plasmid containing foreign DNA have DNA of two species.
