Genetically engineered viruses are being developed that can still confer immunity. So, statement 1 is NOT correct. A clonal colony or genet is a group of genetically identical individuals, such as plants, fungi, or bacteria. Since genetic engineering can be done with bacteria, it can also be done with clonal bacteria. So, statement 2 is NOT correct. Filamentous fungi are widely used in biotechnology as cell factories for the production of chemicals, pharmaceuticals, and enzymes. Statement 3 also can't be the answer. So, statement 3 is NOT correct.
