Answer:
The manipulation of DNA within cells to improve the production of materials or the material itself is called genetic engineering
Step-by-step explanation:
Genetic engineering is the use of recombinant DNA to transform the genetic composition of an organism. Generally, humans have indirectly manipulated the DNA through reproduction control, for example, the selection of offspring that have the desired characteristics. Genetic engineering involves the manipulation of one or more genes. A gene from another species is introduced into the genome of another organism so that the desired phenotype is produced.
