Human telomere sequences are composed of several kilobases of (TTAGGG) n repeats followed by long single-stranded (ss) overhangs at the 3′ end of the G-rich sequences, called G-overhangs. Maintaining ...
Half a century ago, scientists Jim Watson and Alexey Olovnikov independently realized that there was a problem with how our DNA gets copied. A quirk of linear DNA replication dictated that telomeres ...
Undergraduate biology students could be forgiven for thinking that scientists have DNA replication all figured out. After all, textbooks present the models of replication so matter-of-factly that it's ...
