UPSC IAS – 2019
B) While gene editing tools *could* potentially be involved in developing biosensors, Cas9 itself is not primarily a biosensor.
C) Cas9 is a tool for editing genes, not a gene that confers pest resistance directly, although it could be used to insert or modify genes to make plants pest-resistant.
D) Cas9 is a protein used for DNA modification, not a herbicidal substance.
