Telomere biology disorders (TBDs) are a spectrum of genetic disorders caused by pathogenic or likely pathogenic (P/LP) rare germline variants in genes encoding essential components of telomere maintenance. Telomeres consist of long nucleotide repeats (TTAGGG)n and a protein complex at chromosome ends...

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 ...
How are chromosomes organized in eukaryotes? What is the role of telomeres in eukaryotic chromosomes, and where would you expect to find them? Why is the coiling of the chromosome necessary to accomplish cell division? During interphase, the chromosomes are not visible using a light microscope. ...
Telomere biology disorder (TBD). One of a set of pathologies that are defined by the presence of short telomeres. Chromothripsis A mutational phenomenon that involves catastrophic shattering and rebuilding of chromosomes, leading to multiple clustered chromosomal rearrangements. Kataegis Clustered point muta...

by looking at the length of the telomeres on specific chromosomes, we can actually predict, pretty much…how long certain cells can successfully go on dividing.Now there are some cells that just seem to keep on dividing, regardless…which may not always be a good thing if it gets out of ...
