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.
Generally, the path to becoming a CRNA begins with a 4-year undergraduate degree in nursing or another field. Although it is not required to possess a degree in nursing, a current license as a registered nurse is required to enter a nurse anesthesia program.
