Q. The site directed nucleases is recently seen in news is related to?

[A] Genome editing

[B] Space debris

[C] Super Computers

[D] Machine Learning

Answer: A

Explanation: Department of Biotechnology revised guidelines for plants and products thereof developed using genome editing techniques employing site directed nucleases (SDN).

  • SDN or sequence specific nuclease (SSN) refers to the practice of cleaving DNA strands to affect the subsequent genome editing.
  • SDN technology takes advantage of targeted DNA break and host’s natural repair mechanisms to introduce specific small changes at the site of the DNA break.
