state the advantages of the technique involved in the production of transgenic Crop our breeding activities
Answers
Answer:
Crop, whose genetic characteristics have been altered by the insertion of a modified gene or a gene from another crop/organism using the techniques of genetic engineering, is known as transgenic crop. Example: BT Cotton.
Transgenic crops also termed as Genetically modified crops (GMCs),crops, biotech crops & hybrid crops.
These are plants, the DNA of which has been modified using genetic engineering techniques.
In these crops, a gene from some other organism or another plant or a microorganism is inserted into it, to get desired characteristic such as disease resistance, response to fertilizers, product quality and high yields.
For example:
Golden rice is a genetically engineered rice or transgenic rice.
The content of vitamin A is very low in rice. Vitamin A is synthesized from the precursor Carotenoid which is synthesized by 3 genes. Prof. Ingo and Prof. Beyer produced genetically engineered rice by introducing these 3 genes associated with biosynthesis of carotenoid. The transgenic rice was rich in pro vitamin A. Since the seeds of transgenic rice are yellow in colour due to pro vitamin A, the rice is commonly known as “Golden Rice”.Explanation:
