The pulse oximeter is another common piece of medical measuring equipment, designed to measure pulse rate and oxygen saturations by pegging onto a patient's finger. They are used on almost every hospital patient at least daily, and so are highly prone to transmitting. .
Why is DNA replication important? A: DNA replication is important because it creates a second copy of DNA that must go into one of the two daughter cells when a cell divides. Without replication, each cell lacks enough genetic material to provide instructions for creating proteins essential for bodily function.
RNA plays a central role in the pathway from DNA to proteins, known as the  Central Dogma  of molecular biology. An organism's genetic information is encoded as a linear sequence of bases in the cell's DNA. During the process known as transcription, a RNA copy of a segment of DNA, or messenger RNA (mRNA), is made. This strand of RNA can then be read by a ribosome to form a protein. RNAs also play important roles in protein synthesis, as will be discussed in the ribozyme section, as well as in gene regulation.
