Mitosis is a form of eukaryotic cell division that produces two daughter cells with the same genetic component as the stem cell. During this process, chromosomes replicated during S phase are divided in such a way as to ensure that each daughter cell receives a copy of each chromosome. This process usually takes about an hour in actively dividing animal cells. The result of this division is duplicate nuclear material, also known as chromatin.
A nuclear stress test is a medical procedure that uses a radioactive tracer to measure the blood flow to your heart. Learn how long it stays in your system and the risks associated with it.
Nuclear scanning is a medical procedure that uses radioactive material to create images of the body. Learn about the basics of nuclear scanning, its associated health risks, and how to minimize those risks.
