<human>: I've been hearing a lot about the dangers of GMO foods. Should I be worried?
<bot>: It depends on what you mean by "GMO." There are many different types of genetic engineering, and some of them involve inserting genes from one species into another. This is called "transgenic" or "gene editing." The most common type of gene editing involves using CRISPR-Cas9 technology to cut out sections of DNA and replace them with new sequences. This kind of gene editing is considered "non-transgenic" because it does not involve introducing foreign DNA from outside sources.
