 [HOME > OUTLINE > HOW BIOTECH WORKS]      
From the educational point of this site,it will be more interesting to show the idea of biotechnology that made a great revolution in different fields of life. As it will explain to the readers how biotechnology works, and so it will make the rest of the site clear to them.

  The DNA (deoxyribonucleic acid) is common in all organisms, it is found in the chromosomes inside the nucleus of a cell, it directs the cell to make the proteins that are the basis of life. Throughout the years, researchers have discovered how to transfer a specific piece of DNA from one organism to another A researcher's first step in transferring DNA is to "cut" or remove a gene segment from a chain of DNA using enzyme "scissors" to cut at a specific site along the DNA strand.  The researcher then uses these "scissors" to cut an opening into the plasmid — the ring of DNA often found in bacteria outside of a cell. Next, the researcher "pastes" or places the gene segment into the plasmid. Because the cut ends of both the plasmid and the gene

segment are chemically "sticky," they attach to each other, forming a plasmid containing the new gene. To complete the process, researchers use another enzyme to paste or secure the new gene in place.
