What was a major breakthrough in recombinant DNA technology and how did it impact the applications of this technology?

The discovery of restriction enzymes was a major breakthrough. These enzymes allow the cutting of DNA molecules at specific regions, expanding the applications of rDNA technology to agriculture, pharmaceuticals, and scientific research. Signup and view all the answers

What is the role of tumefaciens in genetic engineering of plants?

It uses the tumor-inducing plasmid of the bacterium to allow the foreign gene to be incorporated into the genome of the host plant. Signup and view all the answers

How does genetic modification of animals differ from genetic modification of plants?

Genetic modification of animals involves the injection of hundreds to thousands of copies of the foreign gene to the zygote, resulting in a genetic mosaic. Signup and view all the answers

What is the continuous effort in recombinant DNA technology and what are its potential applications?

Recombinant DNA technology continuously strives to improve methods in identification, isolation, and introduction of the gene of interest. It also identifies novel applications to address concerns in agriculture, pharmaceuticals, and medicine. Signup and view all the answers
