Crops like potato, tomato, soybean and rice are currently being genetically engineered to obtain new strains with better nutritional qualities and increased yield. The genetically engineered crops are expected to have a capacity to grow on lands that are presently not suitable for cultivation. The manipulation of the genes in crops is expected to improve their nutritional value as also their rate of growth. Biotechnology, the science of genetically engineering foods, can be used to impart a better taste to certain foods.
Engineered seeds are resistant to pests and can survive in a relatively harsh climatic conditions. The recently identified plant gene known as At-DBF2, when inserted in tomato and tobacco cells is seen to increase their endurance to harsh soil and climatic conditions. Biotechnology can be used to slow down the process of food spoilage. It can thus result in fruits and vegetables having a greater shelf life.
genetic engineering in food can be used to produce totally new substances such as proteins and other food nutrients. The genetic modification of foods can be used to increase their medicinal value, thus making available homegrown edible vaccines.
... to believe is important to our health and safety. Genetically engineered foods containing genes resulting from bacteria and viruses are now ... chemicals that are affecting crops like, corn, potatoes, and soybeans. There is controversy with genetically altered foods due to the ... past five years scientists have been trying to genetically modify foods, and crops by removing and adding certain genes. This ...
Genetic engineering has a great potential of succeeding in case of human beings. This specialized branch of genetic engineering, which is known as human genetic engineering is the science of modifying the genotypes of human beings before birth. The process can be used to manipulate certain traits in an individual.
Positive genetic engineering deals with enhancing the positive traits in an individual like increasing longevity or human capacity while negative genetic engineering deals with the suppression of the negative traits in human beings like certain genetic diseases. Genetic engineering can be used to obtain a permanent cure for certain dreaded diseases.
If the genes responsible for the exceptional qualities in some individuals can be discovered, these genes can be artificially introduced into genotypes of other human beings. Genetic engineering in human beings can be used to change the DNA of individuals to bring about desirable structural and functional changes in them.
