WebApr 3, 2024 · When generating a DNA profile, forensic scientists don’t analyze the entire genetic sequence. Instead, they look at roughly 40 short segments of DNA that vary from person to person. Those different variations are called alleles, and the key to knowing a person’s DNA profile is knowing which alleles they have. WebOct 28, 2024 · Scientists and physicians are working to use CRISPR/Cas9 to treat diseases by targeting and correcting these DNA mistakes. This type of treatment for diseases is called gene therapy and, since it is very new, it has not been fully tested on humans yet.
