A. BMI is the correct answer
Answer:
Gave scientists a tool used for genetic engineering
Explanation:
Recombinant DNA technology usually used in genetic engineering. Genetic engineering is the branch of biology in which all genetical things are studied. By using genetic engineering, it is possible to create new animals, to remove unwanted nature from any organism, improve any character in any species, etc.
Recombinant DNA technology helps to combine two genes from two different species. By doing this, it is possible to remove any weak character from any species such as a species of rice that is susceptible to Rice hispa; another species of rice has that gene that is resistant to Rice hispa. Now, by using Recombinant DNA technology, it possible to take the resistant gene and insert it to that species, which is susceptible to Rice hispa. It will improve that susceptible variety.
