Telomerase activity is controlled during development and is extremely low in somatic (body) cells, virtually undetectable. These somatic cells age because they do not frequently use telomerase.
- Telomeres are repetitive sections at the very ends of chromosomes that are present in a variety of eukaryotic species, including humans and unicellular protists.
- Each round of DNA replication wears down a little portion of the telomeres, which serve as caps to safeguard the interior chromosomal regions.
- Most somatic (body) cells do not typically have telomerase activity, but certain adult stem cells and germ cells—the cells that produce sperm and eggs—have.
- Adult germ cells, tumor cells, and fetal tissues all contain telomerase. Telomerase activity is controlled during development and is extremely low in somatic (body) cells, virtually undetectable. These somatic cells age because they do not frequently use telomerase.

<h3>What is way of testing medicines?</h3>
In a laboratory, drugs are first subjected to non-human tests. These laboratory tests are performed to determine a level of safety.
The results of these tests are then submitted to the United States Food and Drug Administration (FDA), which determines whether the treatment is safe enough to be studied in human volunteers.
There are various phases involving discovery, clinical trial, review, and safety monitoring.
