Telomeres in Disease
By Rodrigo Calado and Neal Young
Telomeres have been linked to numerous diseases over the years, but how exactly short telomeres cause diseases and how medicine can prevent telomere erosion are still up for debate.
Telomere Basics
By Rodrigo Calado and Neal Young
Telomeres are repetitive, noncoding sequences that cap the ends of linear chromosomes. They consist of hexameric nucleotide sequences (TTAGGG in…
