What are Genetically Modified Crops
For thousands of years we have tried to select plants for improved yield, growth or food characteristics. In the past, this has been done by selective breeding, selecting the plants with desired characteristics and crossing it with another plant with other desired characteristics. As a result a new variety of the plant formed at a much faster rate that would occur in the wild. The problem with this was when plants were crossed with ancestral varieties, the embryos do not survive very well. Another problem was that only plants in the same species are able to cross with each other. So Scientists wanted to find a way around this. The characteristics of plants are determined by its DNA, which is a genetic code of its features. Just like a blueprint it contains even tiny details, like how even individual cells are constructed. The DNA is then divided up into sets of genes, which are instructions for individual functions. The characteristics of each plant are determined by which genes it has received from its parent plants, whether or not these genes are expressed and interactions between the genes and environmental factors. With modern genetic modification genes can be selected, isolated and inserted into another plant, without th
