Detailed explanation-1: -What kind of genetically modified crops would be most successful in wet-tropical countries that are overcrowded? High-yield crops that are pest-resistant. In what way did gene therapy, the replacement of a faulty gene with a normal one, stimulate medical research?

Detailed explanation-2: -4.5. Gene replacement therapy is the technique of recognizing a faulty gene, applying a piece of DNA in its correct form though a viral vector (known as the carrier molecule) to the gene, thus overriding the identified faulty gene with the correct copy.

Detailed explanation-3: -In Agriculture: Genetically modified crops are produced using genetic engineering in agriculture. Such crops are produced that provide protection from insect pests. It is used or can be used in the creation of fungal and virus-resistant crops.

Detailed explanation-4: -Genetic engineering is guaranteed to make a change. Many of those changes are positive, creating more and healthier foods. Some of those changes, however, can be negative and unexpected. Making a plant become more tolerant to drought might also make that plant become less tolerant to direct sunlight.
