What is a chromosome? In the nucleus of each cell, the DNA molecule is packaged into thread-like structures called chromosomes. Each chromosome is made up of DNA tightly coiled many times around proteins called histones that support its structure. Chromosomes are not visible in the cellâs nucleusânot even under a microscopeâwhen the cell is not dividing.
Once candidates have completed the CNA program required in the state they want to practice in, they will have to pass a state certification exam to receive their professional credential. Generally, nursing assistants are not expected to have previous work experience before they become certified.
In many other states the certification is known as Certified Nursing Assistant, or CNA. The first step to get your certification is to attend STNA classes. These STNA classes are required to include at least 59 hours of classroom training and 16 hours of clinical training. Once you have completed your course, you will then be ready to take your test. There are two sections of the Ohio STNA test.
