Answer 2

It is the method used to identify the presence of complementary nucleic acid sequences.

• The innovative method helps to form target sequences by hybridization.
• It is useful in biotechnology as -

1. It is used in a variety of industries, including food, medicine, veterinary medicine, the environment, and security, with the goal of preventing, diagnosing, and treating diseases.
2. When utilised in appropriate settings, these can be used to identify microorganisms, including disease detection, and quantify them.
3. It helps in the rapid detection and identification of infectious agents, and the discovery of nonviable or difficult-to-culture organisms.
4. It also holds the capacity to screen chosen specimens employing sets of probes
