Question:

Transgenic plants are the ones

Updated On: Aug 1, 2022
  • Grown in artificial medium after hybridization in the field
  • Produced after protoplast fusion in artificial medium
  • Produced by somatic embryo in artificial medium
  • Generated by introducing foreign DNA into a cell and regenerating a plant from that cell

The Correct Option is D

Solution and Explanation

The plants produced through genetic engineering contain gene or genes usually from an unrelated organism. Such genes are called transgenes and the plants having transgenes are called transgenic plants. Recombinant DNA techniques are being used to improve crop plants by increasing their productivity, by making them more nutritious, and by developing disease resistance. Transgenic plants have a natural resistance to herbicides and pests. In the future, plants may have an ability to fix atmospheric nitrogen and an increased ability to grow in arid and salty soils.

Concepts Used:

Applications of Biotechnology

Biotechnology is the technology that utilizes biological systems, living organisms, or parts of this to develop or create different products.

For example, brewing and baking bread fall within the concept of biotechnology (use of yeast (= living organism) to produce the desired product).

Agriculture

Alternative to conventional farming: A possible solution is the use of genetically modified crops which is an alternative path to conventional farming.

Medicine 

In the area of healthcare, recombinant DNA technological processes have made an immense impact which enables the mass production of safe and more effective therapeutic drugs.

Gene Therapy 

A collection of methods that allows the correction of a gene defect that has been diagnosed in a child/embryo is called Gene Therapy.

CRISPR technology

For editing genomes, CRISPR is a simple yet powerful tool which allows researchers to easily alter DNA sequences and modify gene function.
