Question

one main use of genetic engineering is to...
a remove all unwanted tissues and organs
b create dna fingerprints
c insert new genes into organisms
d duplicate whole organisms

Explanation:

• Option a: Removing unwanted tissues/organs is not a main use of genetic engineering (more related to surgery).
• Option b: Creating DNA fingerprints is part of DNA profiling, not genetic engineering’s main use.
• Option c: Genetic engineering involves manipulating an organism's genome, often by inserting new genes to give desired traits (e.g., transgenic organisms).
• Option d: Duplicating whole organisms is cloning (a specific application, not the main use of genetic engineering broadly, and genetic engineering is more about gene-level manipulation than whole - organism duplication).

Answer:

c. insert new genes into organisms
