MCQ
Transgenic plants are the ones
  • generated by introducing foreign $DNA$ into a cell and regenerating a plant from that cell
  • B
    produced after protoplast fusion in artificial medium
  • C
    grown in artificial medium after hybridization in the field
  • D
    produced by a somatic embryo in artificial medium.

Answer

Correct option: A.
generated by introducing foreign $DNA$ into a cell and regenerating a plant from that cell
a
(a) : 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.
