GENE REVOLUTION
Every plant animal and person consists of cells. Each of the is tiny but has its own even smaller world. In the heart of this world is a special code, which controls cell’s identity. Information about cell’s functions is in the cell’s genes.
There are about 100.00 of genes in a human being. Each of them is made of molecules. Scientists knew about genes for a long time but only recently discovered how to control them. Genetic engineers discovered what genes do which of them control growth eye colors intelligence and so on. But new even bigger project is underway. Scientists have started to decode human body’s genome.
When it is finished, we’ll have a full map of mankind’s genetic identity. It will help to cure many diseases. But it won’t stop there. Once we understand how genes work, we’ll have many new choices to make.
Possibilities like perfect babies concern many experts. Some say they will be a huge step into future some think the opposite.
In animal research, genetic control has already begum in the form of cloning.
