Question

What are GM crops ??
Why is this method used nowadays ??​

Answer 1

Explanation:

Genetic modification (GM) technology allows the transfer of genes for specific traits between species using laboratory techniques. ... Most current GM crops grown in the U.S. are engineered for insect resistance or herbicide tolerance. Corn, soybeans, and cotton are the three largest acreage GM crops.

Answer 2

1. Genetically modified crops are plants used in agriculture, the DNA of which has been modified using genetic engineering methods. Plant genomes can be engineered by physical methods or by use of Agrobacterium for the delivery of sequences hosted in T-DNA binary vectors.
2. To increase the annual harvesting productivity,the modern techniques of artificial vegetative reproduction is often used nowadays. This artificial reproduction helps to tweak in the biological characteristics of the harvesting products,in order to make them disease resistant and to increase the annual productivity
