Reading an EKG is done by careful viewing of the EKG strip. This  includes assessment of rhythm regularity, calculating heart rate,  observing the form of various parts of tâ¦he EKG and their timing.
This process of cell culture or tissue culture requires a method to dissociate the cells from the container and each other. Trypsin, an enzyme commonly found in the digestive tract, can be used to digest the proteins that facilitate adhesion to the container and between cells.his process of cell culture or tissue culture requires a method to dissociate the cells from the container and each other.

When RNA viruses invade the human organism, they inject their RNA into the cytoplasm of the host cell. Once they are inside the cytoplasm, RNA can be used to synthesize proteins, and, eventually, to form replica viruses. There is a special category of RNA viruses, which is called retroviruses. These viral agents contain protein known in biology as reverse transcriptase. Once the retrovirus injects its RNA into the cell, reverse transcriptase transcribes the RNA into DNA (the operation that is the reverse of normal transcription).
