Question

What are Transgenic crops?

Answer 1

As we knew that transgenic crops or genetically modified crops are crops that are artificially made. The crops or plants are modified at the genetic level using genetic engineering techniques. Plant genes can be modified physically or by use of Agrobacterium for the results of sequences by T-DNA vectors. Transgenic crops are of greater use than the ordinary ones.

Complete answer:
Generally, farmers nowadays produce modified crops because this is done to protect crops from pests, insects and other diseases which can affect plants resulting in reduced productivity. Transgenic crops major factors seen in crops are their high yielding content, crops tend to produce more and better qualities of content when they are introduced into genetic techniques.
There are many disadvantages also in consuming the modified crops. Transgenic crops examples are paddy, tomato, sorghum, cotton, corn, papaya, brinjal etc.
The aim is to introduce the new traits into the crops is simple as the natural species of crops are not desired. Crops have more management problems that require more handling. They are reduced to spoilage, can withstand adverse environment conditions, resistance to chemical treatments like a certain herbicide or they have high nutrient profile.
example of BT brinjal- The modified BT brinjal (BT means Bacillus thuringiensis) in India has been developed for insect or pest resistance. By gene-splicing BT toxin genes were separated from Bacillus thuringiensis and incorporated into several crop plants.
The eggplant or transgenic brinjals has been created by inserting a crystal protein gene (cryAC) from the bacterium Bacillus thuringiensis into the genes of brinjal cultivars.
Exploitation is done by taking away the healthy plant solution made in the laboratory and replacing it with ordinary. The formula and credits are also being stolen if not being patented. Patronizing the crops is very important.

Note:
The Effectiveness of the crop against pests is quite satisfactory. The larvae of the insect feed on the BT brinjal plant, they ingest the BT protein CryA1C along the plant tissue. Within the insect gut which is alkaline in nature is solubilized and activated by the gut proteases. The protein binds to specific receptor proteins present within the insect membrane which make pores in the gut leading to disruption of digestive paralysis and death of the larvae.
