Scientists have known since 1952 that DNA is the basic stuff of genetics. They know that human DNA acts like a biological computer program that spells out the instructions for the synthesis of proteins, the basic building blocks of life.
In this unit we are going to probe into the mysteries of genetic engineering. Passage A offers a general review of the development in genetic engineering, its prospective benefits and latent perils. Passage B goes into detail about genetic engineering and its potential impact on people's lives. Passage C, "Understanding the Genome Is Only the Beginning", as the title suggests, provides more information about how genetic knowledge will affect various aspects of our lives.
