...lication of telomeric DNA. Thus, telomeres become shorter as we age. In most tumor cells, telomerase is active and telomere length is stabilized. The current hypothesis is that telomere length acts as a clock to limit the total number of divisions any cell is capable of achieving. This limitation ...UC Berkeley psychologist finds evdence that male hormones in the womb affect sexual orientation
