This figure depicts the enzyme telomerase as well as telomeres relative to a chromosome.
Can we stay young forever, or even recapture lost youth? Can we stay young forever, or even recapture lost youth? Research from the laboratory of Professor Julian Chen in the School of Molecular Sciences at Arizona State University recently uncovered a crucial step in the telomerase enzyme catalytic cycle. This catalytic cycle determines the ability of the human telomerase enzyme to synthesize DNA “repeats” (specific DNA segments of six nucleotides) onto chromosome ends, and so afford immortality in cells. Understanding the underlying mechanism of telomerase action offers new avenues toward effective anti-aging therapeutics.
Typical human cells are mortal and cannot forever renew themselves...
