Question

Which is not one of the major categories of biotechnology products?
A. Hormones and similar proteins
B. Toxins for use in pest control
C. DNA probes
D. Vaccine

Answer 1

Biotechnology is the application of biological systems found in organisms, or the utilisation of living organisms themselves, to achieve technical advancements and adapt those advancements to diverse industries. These include uses in a variety of industries, ranging from agriculture to medicine.It encompasses not only applications in domains involving living things, but also any other field in which knowledge received from an organism's biological component can be applied.

Complete answer:
Option A: Recombinant DNA technology has produced vaccines, antibiotics, and hormones, among other things. Transgenic plants are typically designed to increase crop plant traits.
So, option A is not correct.
Option B: Biotechnology is the use of biological processes for industrial and other purposes, including genetic modification of microbes for the creation of antibiotics, hormones, and vaccines, among other things. It also includes a variety of other techniques such as DNA probe creation and amplification. Biotechnology, rather than producing chemicals for pest management, involves genetically altering plants' genomes to make them pest resistant.
So, option B is correct.
Option C: DNA probes are single-stranded DNA segments that are hybridised to detect the presence of complementary nucleic acid sequences (target sequences). To make DNA probes detectable, they are frequently labelled with radioisotopes, epitopes, biotin, or fluorophores.
So, option C is not correct.
Option D: Biotechnology advancements have made it possible to create vaccinations that do not transmit a virus or bacteria. This technology has aided in the development of more than twenty new vaccinations against infectious agents, as well as the improvement of current vaccines and the expansion in vaccine production capacity.
So, option D is not correct.

Hence, Option B is the correct answer.

Note:
Biotechnology has recently resulted in the development of novel pesticides that manage a wide range of pests. These biologically produced pesticides, which rely on the natural pest-fighting skills of a wide range of plants and bacteria, have characteristics that set them apart from traditional chemical pesticides. The creation of insect-specific poisons in resistant crops and trees, the development of microbiological agents with increased insecticidal potency, and the engineering of insects that may convey fatal genes are all possibilities to natural populations following their mass extinction are all examples of insect biotechnological applications in pest management.
