Question

Bt brinjal is an example of transgenic crops. In this, Bt refers to
A. Bacillus tuberculosis
B. Biotechnology
C. β Carotene
D. Bacillus thuringiensis

Answer 1

Hint: One can say that a transgenic crop is nothing but a hereditarily changed creature. The transgenic shows that an exchange of potentials has occurred, exploiting recombinant DNA invention. It is said that at least one quality is embedded falsely in transgenic crops. These false characters are either from an irrelevant plant or from various species inside and out.

Complete answer: The hereditarily altered brinjal is a set-up of transgenic brinjals made by embeddings a precious stone protein quality (Cry1Ac) from the dirt bacterium Bacillus thuringiensis into the genome of different brinjal cultivars. The addition of the quality, alongside other hereditary components, for example, advertisers, eliminators, and an antimicrobial opposition marker quality into the brinjal plant are cultivated utilizing Agrobacterium-interceded hereditary change.
To give obstruction against lepidopteran insects, specifically the Brinjal Fruit and Shoot, the Bt brinjal has been created
Mahyco, an Indian seed organization situated in Jalna, Maharashtra, has built up the Bt brinjal.
Bacillus thuringiensis is a Gram-positive, soil-abiding bacterium, ordinarily utilized as a natural pesticide. B. thuringiensis likewise happens normally in the gut of caterpillars of different kinds of moths and butterflies, leaf surfaces, oceanic conditions, creature excrement, bug rich conditions, and flour plants and grain-storerooms. It has likewise been seen to parasitize different moths, for example, Cadra calidella—in research center analyses working with C. calidella, a significant number of the moths were sick because of this parasite.
Hence, Option (d) Bacillus thuringiensis is a correct answer.

Additional Information:
Mycobacterium tuberculosis (M. TB) is a type of pathogenic microscopic organism and a causative specialist of tuberculosis. First found in 1882 by Robert Koch, M. tuberculosis has an abnormal, waxy covering on its phone surface essentially because of mycolic acid.
Biotechnology uses natural frameworks, living life forms, or parts to create or make various items. Preparing and heating bread are instances of cycles that fall inside the idea of biotechnology.
Beta carotene is a red-orange shade found in plants and organic products, particularly carrots and vivid vegetables. It is the yellow/orange shade that gives vegetables and organic products, their rich tones.

Note:
The bacterium Bacillus thuringiensis has a short fragment called the Bt gene, otherwise called the Cry gene. This quality is engaged with the creation of a glasslike item called Bt. The item demonstrates poisonous when ingested by the vermin. The protein becomes actuated once it arrives at the vermin's gut and makes pores in the digestive system. This has a murdering impact. Hereditary designing strategies bring this gene into crops like cotton, brinjal, and so on. These become transgenic crops, otherwise called GMO. Henceforth, the Bt quality is utilized to give GMOs security against budworm, bollworm, insects, drill, and so on.
