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.
Step 1: Complete a Nursing Degree or Certificate Program. In order to become a clinic nurse, candidates typically first earn either a Bachelor of Science in Nursing (BSN), associate's degree in nursing (ADN) or LPN certificate. An LPN certificate typically takes a year to earn. An ADN takes around two years to earn, and a BSN can usually be earned in four years.
