One of the broken strands jumps into Dad's. Reads what nucleotides are missing, fixes the gap, then jumps back in to its broken DNA strand. Now it's used as a template to fix its original broken strand, and now it's fixed. And that's a very more specific, directed way of fixing the DNA to remove errors. So, basically, what you can do is through this CRISPR technology that we've hijacked from the bacteria.
In this episode, Dr Matt and Dr Mike discuss how humans realised that bacteria could fight off viruses using sequences in their DNA called, CRISPR. Today, CRISPR technology is being used to cure cancer and investigate the cause of genetic disease.
