What term describes organisms whose DNA has been engineered?

Explanation:
DNA engineering means scientists deliberately alter an organism’s genetic material to introduce or change traits. The term for these organisms is genetically modified organisms. This reflects the intentional modification of genes using biotechnological methods such as gene insertion, deletion, or editing. Clones are about producing genetically identical copies, not about engineering new traits. Mutants refer to organisms with mutations, which can occur naturally or be induced, not necessarily through deliberate engineering. Hybrids are offspring from crossing different species or varieties, combining genomes rather than inserting engineered genes. So, genetically modified organisms is the best description.
