Q. The “CRISPR Cas – 9” is often seen in news is related to which of the following?

[A] Genetic modification

[B] Outer space planet

[C] Hybrid vehicle technology

[D] Soil less farming

Answer: A

Explanation: CRISPR is a genetic code or sequence found in bacteria. These are formed due to the activity of the previous bacteriophages that had infected them.

  • Bacteria use CRISPR sequence to remember each specific virus that attacks them. They do this by incorporating the virus’ DNA into their own bacterial genome.
  • This method then gives the bacteria protection or immunity when a specific virus tries to attack again. Cas 9 are the genes that are always located nearby.
