A) Molecular biology
B) Cytogenetics
C) Genetic hybridization
D) Genetic engineering
Correct Answer: D
Solution :
[d] Genetic engineering is the science of gene manipulation. Genetic engineering, genetic modification (GM) and gene splicing are terms for the process of manipulating genes, generally implying that the process is outside the organism's natural reproductive process. It involves the isolation, manipulation, transfer, and reintroduction of DNA into cells or model organisms usually to express a protein. The aim is to introduce new characteristics or attributes physiologically or physically, such as making a crop resistant to a herbicide, introducing a novel trait, or producing a new protein or enzyme, along with altering the organism to produce more of certain traits.
