Question

ANDi is a cloned
A. Sheep
B. Bull
C. Monkey
D. Cat

Answer 1

ANDi is the first transgenic monkey. The gene insertions in the monkey will lead to primate models of human diseases. Plasmid DNA acts as a vector to transfer a piece of alien DNA attached to it.

Complete step by step answer: ANDi is a cloned monkey. It is a coffee-coloured Rhesus monkey engineered to carry a gene from other species. The work demonstrates that a foreign gene can be inserted into a primate chromosome. Vectors are DNA molecules that carry a foreign DNA segment and replicate within host cells such as bacteriophages, cosmids, phagemids, BAC (Bacterial artificial chromosomes), YAC (Yeast artificial chromosome) animal Vectors, plant vectors and shuttle vectors. Just like the mosquito, which acts as an insect vector to transfer the malarial parasite into the human body, the plasmid is used to transfer alien DNA into the host organism. Shuttle vectors are those vectors which can also be used for more than one organisms like used for both prokaryotes and eukaryotes. The gene insertions in the monkey will lead to primate models of human diseases (Alzheimer’s diabetes, heart disease and obesity), which will render more pronounced testing for new drugs, gene therapy and modified stem cells.
Hence, the correct answer is option C.

Note: Modern biotechnology is based on genetic engineering. Foundation of biotechnology is based on two important discoveries:
a. Presence of plasmid in bacteria.
b. Restriction enzymes that can be used in vitro.
