Question

Indian farmers are unhappy over the introduction of ;Terminator Seed Technology' because the seeds produced by this technology are expected to
A. Give rise to sexually sterile plants
B. Form low yielding plants despite the high quality
C. Show poor germination
D. Give rise to the plants incapable of forming viable seeds

Answer 1

Hint: The gene technology of the terminator, or genetic gene is the use of restriction technology. Genetic plant modification to make them grow second generation sterile seeds that are also known as "suicide seeds"

Complete answer:
This technology was developed on the basis of this gene expression mechanism. For this purpose , three stretches of DNA that carry genetic information were introduced into the plant. A unique form of promoter has the first bit of DNA. A promoter is a DNA stretch where it initiates the process of transforming a gene into a protein. Only in the later phases of seed maturation will the promoter used for the terminator genes become active. By inserting DNA strips, plant cells are genetically modified and plants are regenerated by tissue culture techniques. Because only during a certain stage of seed formation is the promoter involved, the lethal gene has no chance of being expressed. The blocking sequence is firmly in place to prevent the lethal gene from being active as the first generation plants go into the seed production market. Therefore, without any difficulty, the first generation seeds are produced.
The crossing of the two factories generates the plants that inherit all DNA strips. The recombination gene is triggered during germination when the first generation seeds are planted and removes the excision and blocking sequences from the first strip of DNA. As in the previous case, only when the plant attempts to produce the second generation seeds, which become sterile as a result, will the lethal gene be triggered.

Hence, the correct answer is option (A).

Note:
The technology is quite relevant to pure lines of open-pollinated varieties and hybrids for sowing, especially in the case of transgenic crops with desirable transgenic, such as "Bt" for insect resistance, disease resistance and herbicide resistance, from this angle. This technology will force farmers to purchase fresh seeds every year, thus increasing the company 's turnover.
