Question

Which is not a transgenic plant?
(A) Soyabean
(B) maize
(C) golden rice
(D) cucumber

Answer 1

Hint: A number of transgenic plants are produced nowadays in large quantities. It is produced in order to increase production and is also used to make the plants resistant to pests or insects and also make the plant resistant to abiotic stresses.

Step by step solution:
  Transgenic plants are those whose genomes have had one or more genes from a different species inserted utilizing genetic engineering techniques. Producing crops with desirable features, excellent quality, and high yield is the core goal of transgenic plant breeding. In addition to helping the agriculture industry, it has been discovered that the plants can serve as a factory for the manufacturing of pharmaceutical proteins. Transgenic organisms, often known as genetically modified organisms (GMOs), are creatures whose genomes have been altered (genetic make-ups). This could be accomplished by microinjecting, which entails transferring DNA from one organism into the nucleus of an egg from another.
When investigating the role of a gene, transgenic organisms are useful to study tools. Transgenesis and gene therapy, a medical procedure in which DNA is inserted into a patient's cells to treat illness, are similar concepts. In agriculture, transgenic organisms are widely used. A transgenic organism is one that has undergone genetic modification using recombinant DNA technology, which either entails the fusion of DNA from various genomes or the introduction of foreign DNA into a genome.
Golden rice is a type of rice created by genetic engineering that allows the edible sections of the grain to generate beta-carotene, a precursor of vitamin A. Two beta-carotene biosynthetic genes, psy (phytoene synthase) from daffodils (Narcissus pseudonarcissus) and crtI (carotene desaturase) from the soil bacterium Erwinia uredovora, were inserted into rice to produce golden rice.
So, option (D) is correct.
Note: The rise of super-pests, allergic reactions, and biodiversity loss are the main drawbacks of transgenic plants. It raises the expense of cultivation and makes farming more prone to marketization, which focuses on unethical profits.
