(TNS) A new $89 test claims to calculate the age of the DNA in your cells and tell you how well you are aging. The test, called TeloYears, is the newest in a bunch of mail-order kits that measure the length of telomeres, the caps that cover the ends of chromosomes.
Telomeres are often described as the biological equivalent of the plastic caps at the ends of shoestrings which prevent threads from fraying. Made of DNA and protein, telomeres protect chromosomes from damage and from sticking to one another.
