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.
Another minor difference is that DNA uses the base thymine (T) in place of uracil (U). Despite great structural similarities, DNA and RNA play very different roles from one another in modern cells. 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.
