alteplase Alteplase is an enzyme that occurs naturally in man and causes blood clots to dissolve. It is a man-made protein manufactured by recombinant DNA technology. The naturally occurring protein, known as tissue plasminogen activator (TPA), is made by ovarian cells from the Chinese hamster. The amount that is given to patients is far greater than the amount naturally made by the body itself. Alteplase was first approved for heart attacks in 1987. In 1996, it was approved for strokes. PRESCRIBED FOR: Alteplase is used to treat persons with heart attacks (acute myocardial infarctions), strokes, chest pain at rest (unstable angina), blood clots in the lungs (pulmonary thrombosis or embolism), and other less common conditions involving blood clots.

- 1 Telomerase is an enzyme that adds the TTAGGG telomere sequence to the ends of chromosomes. 2  Telomerase is only found in very low concentrations in our somatic cells. Because these cells do not regularly use telomerase they age leading to a reduction in normal function.  The result of ageing cells, is an ageing body.

What Is a Bacteriophage? Temperate viruses are those that reproduce without killing their host cell. Typically they reproduce in two ways: through the lytic cycle and the lysogenic cycle. In the lysogenic cycle, the phage's DNA recombines with the bacterial chromosome. Once it has inserted itself, it is known as a prophage. A host cell that carries a prophage has the potential to lyse, thus it is called a lysogenic cell. The image above illustrates both the lytic and lysogenic cycles of a bacteriophage.
