Question: Genetic engineering is possible, because [CBSE PMT 1998; AFMC 1999]
Options:
A) The phenomenon of transduction in bacteria is well understood
B) We can see DNA by electron microscope
C) We can cut DNA at specific sites by endonucleases like DNAase-I
D) Restriction endonucleases purified from bacteria can be used in vitro
Show Answer
Answer:
Correct Answer: D
Solution:
Genetic engineering is the manipulation of genetic material of an organism using enzyme restriction endonuclease.
