February 14, 2022In human blood cells, the length of telomeres steadily declines over time from 8,000 base pairs at birth to 3,000 base pairs as people age, and as low as 1,500 in the elderly (an entire chromosome has about 150 million base pairs). Each time a cell divides, an average person loses 30 to 200 base pairs from the ends of that cell’s telomeres.
