Which one of the following pesticides is banned now-a-days?
1 DDT
2 Eldrin
3 Aldrin
4 Toxaphene
Explanation:
Exp: DDT (Dichloro Diphenyl Trichloroethane) a chemical pesticide did not decompose radially and persisted in the environment. Since, it was soluble in fat rather than water. It biomagnified up the food chain and disrupted calcium metabolism in birds, causing egg shells to be thin and fragile. So, DDT is banned now-a-days.

The strategy used to prevent the nematode infection in the roots of tobacco plant is called
1 use of agro chemicals
2 bt toxin gene
3 gene mutation
4 RNA interference
Explanation:
Exp: RNA interference (RNAi) is a biological process that can be used to prevent nematode infection in the roots of tobacco plants and other crops. It involves the regulation of gene expression by inhibiting the translation of specific genes into proteins.

Select the wrong statement
1 Human insulin is being commercially produced from a transgenic species of Escherichia coli
2 The genetically modified bacillus thuringiensis is used as biopesticide the commercial scale
3 Human protein, alpha-1-antitrypsin is used to treat emphysema
4 The first transgenic cow, Rosie, produced alpha lactalbumin, enriched milk
5 Bt toxin genes Cry $1 \mathrm{AC}$ control the corn borer
Explanation:
: Bt toxin genes are indeed used in genetically modified crops to make them resistant to certain pests like the Corn borer. However, the specific gene mentioned here, Cry $1 \mathrm{AC}$, is more commonly associated with cotton crops. Cotton plants are genetically modified to produce Cry $1 \mathrm{AC}$, which is toxic to cotton bollworm but not the Corn borer.

Which vaccine is produced by using genetically modified yeast?
1 Polio
2 BCG
3 Hepatitis-B
4 Covaxin
Explanation:
Exp: Hepatitis-B is mainly produced by the Yeast to form a recombinant DNA. HB antigen producing gene is ligated to the plasmid. Then it is inserted to the Yeast cell. In the fermentation tank recombinant molecule multiplies to produces HB antigen. After that antigens are purified and used as hepatitis-B vaccine.
