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.

Once inside the host cell cytoplasm, the virus uses its own reverse transcriptase enzyme to produce DNA from its RNA genome, the reverse of the usual pattern, thus retro (backwards).nce these have been bound, the cell membrane degrades, becoming part of the host cell, and the RNA strands and enzymes go into the cell (3). Within the cell, reverse transcriptase creates a complementary strand of DNA from the retrovirus RNA and the RNA is degraded; this strand of DNA is known as cDNA (4).
