Blood pressure is always given in the form of two numbers, one over the other, like a fraction. The systolic pressure is the upper number, and the diastolic pressure is the lower number. Both of these measurements are important. For example, a personâs BP reading may be 120/80 mmHg.
Chrysoprase, chrysophrase or chrysoprasus is a gemstone variety of chalcedony (a cryptocrystalline form of silica) that contains small quantities of nickel.Its color is normally apple-green, but varies to deep green. The darker varieties of chrysoprase are also referred to as prase.hrysoprase is cryptocrystalline, which means that it is composed of crystals so fine that they cannot be seen as distinct particles under normal magnification.
From Wikipedia, the free encyclopedia. Telomerase reverse transcriptase (abbreviated to TERT, or hTERT in humans) is a catalytic subunit of the enzyme telomerase, which, together with the telomerase RNA component (TERC), comprises the most important unit of the telomerase complex.Telomerases are part of a distinct subgroup of RNA-dependent polymerases.unction [edit]. Telomerase is a ribonucleoprotein polymerase that maintains telomere ends by addition of the telomere repeat TTAGGG. The enzyme consists of a protein component with reverse transcriptase activity, encoded by this gene, and an RNA component that serves as a template for the telomere repeat.
