A broad area of biology called "biotechnology" uses living things to create new goods that will benefit people. It has uses in a number of industries, including agriculture and medicine. It takes advantage of cellular and molecular processes to create goods and technology that benefit both humans and the environment. A few MCQs on biotechnology are provided in this lesson/video to assist the students to assess their conceptual understanding. Additionally, the solutions are given for your reference.
