...members of this newly defined species can best be spotted after 9 p.m. in gourmet groceries, their Burberry-clothed arms reaching for the arugula or a Le Menu frozen flounder dinner. In the parking lot, they slide into their BMWs and lift cellular phones to their ears before zooming off to their architect- designed houses in the exurbs. After warmly greeting Rover (often an akita or golden retriever), they check to be sure the pooch service has delivered his nutritionally correct dog food. Then they consult the phone-answering machine, pop dinner into the microwave and finally sink into their...
...remarkable transformation takes place. With the help of the enzyme, the naked AIDS virus converts its RNA into double-stranded deoxyribonucleic acid (DNA), the master molecule of life. The molecule then penetrates the cell nucleus, inserts itself into a chromosome and takes over part of the cellular machinery, directing it to produce more AIDS viruses. Eventually, overcome by its alien product, the cell swells and dies, releasing a flood of new viruses to attack other cells, including more helper T cells and macrophages. The immune system, deprived of a crucial number of those vital T cells, is unable to direct...
...host's immune system by insinuating their genetic material into the DNA of the host cell. A retrovirus, however, must first use its enzyme called reverse transcriptase to convert its RNA into a DNA molecule, which can then insert itself into the cell's DNA and order the cellular machinery to begin producing more retroviruses. Or it can remain dormant and invisible to the immune system, / awaiting some signal to begin causing trouble. Hidden in the cell's DNA, says David Baltimore, who shared a Nobel Prize for the discovery of reverse transcriptase, the viruses "have found the perfect niche...
...median, and since the crafty simian had exchanged his notes for mine, I was in for a tough time. Orgo lab second semester could have been called "Fun with Carcinogens." Every chemical I touched is even now burrowing deep inside my genes, doing who knows what mischief to my cellular structure...
