The process of making changes in the DNA code of living organisms is called?

• A. DNA Profiling
• B. Genetic Engineering
• C. GMO
• D. Polyploidy

Answer: (B)

Making intentional changes to an organism’s DNA is genetic engineering. It involves methods that add, remove, or alter genes to achieve a desired trait or outcome, such as inserting a gene from one species into another or editing a gene with CRISPR. This is about changing the genetic code itself, not just reading it. DNA profiling, by contrast, focuses on identifying and comparing DNA sequences to establish identity or relationships, not altering genetic material. A GMO is the organism that results from genetic engineering—the product, not the process. Polyploidy refers to having extra sets of chromosomes, a chromosomal change rather than a gene-by-gene modification of the DNA code.
