Answer:
An dlien DNA is linked with the origin of replication so that this alien piece of DNA can replicate and multiply itself in the host organism. This is known as cloning Advantage.It can produce desired microbes in large quantity Disadvantage.
The Pros of Cloning
Benefits of cloning include being able to create tissue and organs that doctors can use when needed for surgery on the original. If labs can clone and grow only the parts needed, this would eliminate the moral and ethical issues associated with cloning an entire person. Other benefits include growing stem cells, cloning lab mice genetically engineered for the specific study, bringing back extinct species, reproducing a pet that died and cloning livestock for food.
The Cons of Cloning
One of the main drawbacks of cloning is that if the original organism has genetic defects, these transfer to the clone as a copy of the original. The first clone, Dolly the sheep, born to a surrogate in 1996, was a genetic copy of a six-year old sheep. Dolly only lived to six years old herself, the bottom end of a sheep's average life expectancy. At the age of five she developed arthritis, and the researchers put her to sleep at age six because of tumors in her lungs, which may have been in the genome of the original.
