Telomeres: Aging and the “Teflon” Cap at the End of the Chromosome

There are a few things that turn me on. Two of them are mtDNA and telomeres.  Telomeres prevent the ends of chromosomes from fusing when they shouldn’t.  They are sequences at the ends of chromosomes, they can be thousands of sequences long.  Each time a cell divides it loses the outmost telomere for technical reasons.  As subsequent  divisions occur more telomeres are lost and eventually there are no more.  This is causes the cell to stop division in the future.  It is death.

As our bodies age telomeres are eroded until there are no more and the cell dies. Eventually, we die.

About carlos

I'm a curious person, of reasonable intellect, "on the beach" (retired) and enjoying my interest in anthropology, language, civil rights, and a few other areas. I've been a hippie/student/aerospace tech writer in the '60s, a witness to the Portuguese revolution in the ‘70s, a defense test engineer and witness to the Guatemalan genocide in the '80s, and a network engineer for an ISP in the '90s. Now I’m a student and commentator until my time is up. I've spent time under the spell of the Mesoamerican pyramids and the sweet sound of the Portuguese language. I've lived in Europe, traveled in Brazil, Central America, Iceland, New Zealand, and other places. My preferred mode of travel is with a backpack and I eat (almost) anything local. Somehow, many of the countries I have been to have had civil unrest (for which I was not responsible). I'm open to correspond with anyone who might share my liberal, humanist interests. I live in San Buenaventura, California.
