The CPR Basics has the basic steps for CPR. Use it for quick information on hand placement for chest compression, compression rates, compression depth, and ratio of compressions to rescue breaths. The American Heart Association recommends taking a class on how to give CPR and then use the steps below as a reference.
Prophase (from the Greek ÏÏÏ, before and ÏÎ¬ÏÎ¹Ï, stage), is a stage of mitosis in which the chromatin condenses into double rod-shaped structures called chromosomes in which the chromatin becomes visible. This process, called chromatin condensation, is involved with the condensin complex.
Prophase is an involved process and while the chromosomes are visible throughout, they look different depending on the stage of the process the cell is in. During early prophase, the chromosomes are working to condense and shorten in preparation for cell division and they appear under the microscope as a condensed mass; it is hard to distinguish individual chromosomes at this point.
