DNA is a dynamic and adaptable molecule. As such, the nucleotide sequences found within it are subject to change as the result of a phenomenon called mutation. Depending on how a particular mutation modifies an organism's genetic makeup, it can prove harmless, helpful, or even hurtful.

Can DNA be genetically modified?

GM is a technology that involves inserting DNA into the genome of an organism. To produce a GM plant, new DNA is transferred into plant cells. Usually, the cells are then grown in tissue culture where they develop into plants. ... It is these proteins that give the plant its characteristics.

Can you modify human DNA?

Human genetic modification (or “gene editing”) can be used in two very different ways. Somatic genome editing changes the genes in a patient's cells to treat a medical condition. A few gene therapies are approaching clinical use but remain extraordinarily expensive.
