CRISPR /Cas9

  • Crispr/Cas9 is related to genome editing.¬† (Genome: Complete DNA sequence)
  • CRISPR stands for¬†clustered regularly interspaced short palindromic repeats
  • In simple terms, a DNA sequence is cut at a particular spot and then with help of a guide RNA (gRNA) that place is re-made with desired base pairing. This way genes can be altered.
  • It allows scientists to selectively edit genome parts and replace them with new DNA stretches
  • Cas9 is the enzyme which acts as a “molecular scissors” and helps in cutting the DNA sequence.
  • CRISPR is a collection of DNA sequences that direct Cas9 where to cut and paste
