Australian researchers have made a discovery about telomeres that may have implications for aging, heart disease, cancer, and other age-related diseases.
So, what are telomeres?
Each of the chromosomes that store our genetic information has a telomere at each end. This protective cap consists of a specific DNA sequence that is repeated thousands of times and has two purposes: firstly, it protects the coding regions of the chromosomes and prevents them from being damaged, and secondly, it acts as a clock that controls the number of replications a cell can undergo; this is thought to act as a quality control system to ensure that aged and potentially damaged cells do not remain in circulation.
