    • Carol Widney Greider (1961-) 

      Bartlett, Zane (2015-01-26)
      Carol Widney Greider studied telomeres and telomerase in the US at the turn of the twenty-first century. She worked primarily at the University of California, Berkeley in Berkeley, California. She received the Nobel Prize ...
    • Elizabeth Blackburn, Carol Greider and Jack Szostak's Telomere and Telomerase Experiments (1982-1989) 

      Bartlett, Zane (Arizona State University. School of Life Sciences. Center for Biology and Society. Embryo Project Encyclopedia., 2015-03-24)
      Experiments conducted by Elizabeth Blackburn, Carol Greider, and Jack Szostak from 1982 to 1989 provided theories of how the ends of chromosomes, called telomeres, and the enzyme that repairs telomeres, called telomerase, ...
    • The Hayflick Limit 

      Bartlett, Zane (Arizona State University. School of Life Sciences. Center for Biology and Society. Embryo Project Encyclopedia., 2014-11-14)
      The Hayflick Limit is a concept that helps to explain the mechanisms behind cellular aging. The concept states that a normal human cell can only replicate and divide forty to sixty times before it cannot divide anymore, ...
    • Paternal Sperm Telomere Elongation and Its Impact on Offspring Fitness 

      Bartlett, Zane; Yang, Joanna
      Telomeres are structures at the ends of DNA strands that get longer in the DNA of sperm cells as males age. That phenomenon is different for most other types of cells, for which telomeres get shorter as organisms age. In ...
    • Telomerase in Human Development 

      Bartlett, Zane (Arizona State University. School of Life Sciences. Center for Biology and Society. Embryo Project Encyclopedia., 2015-03-23)
      Telomerase is an enzyme that regulates the lengths of telomeres in the cells of many organisms, and in humans it begins to function int the early stages of embryonic development. Telomeres are repetitive sequences of DNA ...
