Yet More on Those Wonderful Telomeres

Protein Clamps Tight to Telomeres to Help Prevent Aging and Support Cancer

ScienceDaily (Sep. 19, 2010) — The number of times our cells can divide is dictated by telomeres, stretches of DNA at the tips of our chromosomes. Understanding how telomeres keep our chromosomes — and by extension, our genomes — intact is an area of intense scientific focus in the fields of both aging and cancer. Now, scientists at The Wistar Institute have published the first detailed report on the structure and function of a crucial domain in the protein known as Cdc13, which sustains telomeres by clamping to DNA and recruiting replicating enzymes to the area.

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.
