As previously mentioned, telomerase exerts its function by maintaining the length of telomeres present at the end of chromosomes that shorten with every cell division. Telomerase is usually not active in somatic cells, as they are mortal and die out after around 50-70 divisions. This occurs as ...
Telomeres are specialized chromatin domains located at the ends of chromosomes. They are involved in chromosome replication, stability and localization in the nucleus. In addition to these functions, recent work suggests that telomeres are involved in such superficially diverse cellular phenomena as ...
Telomeres are nucleoprotein complexes that cap the end of eukaryotic chromosomes. They are essential for the functions and the stability of the genomes. There is now compelling evidences that telomerase, the enzyme that adds elomeric DNA repeats to chromosome end, is an important player in oncogene...
For starters, they have different proteins that are part of the complexes, and these differences define the drastic variance in functions. mTOR is one of the most studies genes that the scientists have known about for decades, however we still don’t know much about how those complexes react ...
We are made out of cells containing DNA—the genetic code which instructs our bodies to perform all the functions necessary for life. The linear DNA strands are bundled up into structures called "chromosomes." Each chromosome containstelomeres, which are caps on the ends of the DNA strands to...
It may seem obvious that we want the clock to tell us something about biological aging at the root level. We are entranced by the sophisticated statistical techniques that bioinformaticists use to derive a clock based on hundreds of different omic factors. But all that has to start with a ju...
Are telomeres a good biomarker for aging? In your answer, describe what would make a good biomarker for aging. List the main physical changes of aging. Explain. How does aging affect muscular size and strength and what factors are in play that determines these effects? What is the non-patho...
The short answer is that stem cells are undifferentiated cells with power to make other kinds of cells. Most cells cannot do that as they can only make more of themselves. What this means is that stem cells can be used to make specialized cells. These include neurons, heart cells, and mo...
