Part 2/11:
Traditional genetic engineering has long revolved around a singular methodology: gene editing. This method allows scientists to make minor adjustments to the genetic blueprint, akin to using a fine pencil to refine an existing drawing. Techniques like CRISPR, a massive leap in precision gene-editing, operate within the universe defined by existing genetic sequences. Think of CRISPR as providing a super-sharp pencil, empowering researchers to make meticulous changes but still limited by the natural constraints of the genome.
