Enzymes, vitamins and hormones can be classified into a single category of biological chemicals, because all of these -
1 Are exclusively synthesized in the body of a living organism as at present
2 enhance oxidative metabolism
3 Are conjugated proteins
4 Help in regulating metabolism
Explanation:
Exp: Enzyme, vitamins and hormones are all important for cellular metabolism. All these categories of biological chemical help in regulation of metabolism. - Enzyme is able to produce protein based catalyst produced by a cell and responsible for the high rate and specificity of one or more intercellular or intracellular biochemical reaction. Vitamins cannot be synthesized in human body and must be procured for diet. - Many vitamins act as coenzymes and are directly required for cellular metabolism because it is fat soluble or activated in exposure of sunlight.

Tobacco plants resistant to a nematode have been developed by the introduction of DNA that is produced in the host cells as
1 An antifeedant
2 A toxic protein
3 Both sense and anti-sense RNA
4 A particular hormone
Explanation:
Exp: Using Agrobacterium vectors, nematode specific genes are introduced into host plants. - The introduction of DNA produces both sense and antisense RNA in host cells. - Antisense RNA can be produced by inverting a DNA copy of m-RNA with respect to the promoter as an expression vector. Transcription from both strands of DNA creates two different RNA molecules on the left, the m-RNA and on the right antisense RNA. - This yields a full length complimentary copy of the mRNA sequence.

Out of the following which is not concerned with biotechnology $?$
1 Biogas production
2 Sewage treatment
3 Bio fertilizers
4 Wood seasoning
Explanation:
Exp: Wood seasoning is not concerned with the biotechnology. It is the process of reducing the moisture content of the wood to the level where it can be used without fear of distortion or cracking. It is basically air drying process of timber. - Biogas is produced by the decomposition of organic matter by the bacteria in anaerobic condition and it is part of biotechnology. - Biotechnology is also very helpful for production of biofertilizers. Biofertilizers enhance soil productivity by fixing atmospheric nitrogen and promote plant growth.

2 $\mathrm{B}, \mathrm{C}, \mathrm{D}$
3 $\mathrm{A}, \mathrm{B}, \mathrm{D}$
4 A, B, C
Explanation:
Exp: Bt toxin or endotoxin are encoded by Cry gene and protein encoded by Cry IAb gene control cornborer - Bt toxin is inactive in nature called pro-toxin converted into active form in gut of insects due to high alkaline condition. - Superweeds are produced by accidently crossing of wild plants with genetically engineered plants. It contains gene for herbicide resistance and such condition is called gene pollution.
