GENOME EDITING

Context:

  • Genome editing and CRISPR-Cas9 has been all over the news in the past couple of years, and with good reasons.
  • CRISPR-Cas9, a gene-editing tool is making gene editing easier and faster than ever, and the possibilities it has opened go well beyond human health.
  • Recently, Indian scientists developed a new variant of CRISPR-Cas9 and showed that it can increase precision in editing genome while avoiding unintended changes in DNA.
  • The researchers showed that this type of gene editing can be used to correct sickle cell anaemia, a genetic blood disorder.
  • The experiments were done in human-derived cells from patients of sickle cell anaemia.
