Kidneys with bad ends

Suh D

  • KMID: 2322081
  • J Korean Soc Pediatr Nephrol.
  • 2008 Apr;12(1):11-22.
Telomeres consist of tandem guanine-thymine(G-T) repeats in most eukaryotic chromosomes. Human telomeres are predominantly linear, double stranded DNA as they ended in 30-200 nucleotides(bases,b) 3'-overhangs. In DNA replication, removal of...
