Telomerase is a reverse transcriptase that uses an RNA template to synthesize telomeres. These repeat sequences bind special proteins that fold the ends of chromosomes back onto themselves to create a stable cap. When this ...
A recent study by George Mason University researchers in the Department of Global and Community Health found that women who have given birth have shorter telomeres compared to women who have not given birth. Telomeres are ...
