Telomerase is an enzyme found inside our cells, which may be related to the aging process. It adds short, repetitive “caps” to our DNA strands. These caps are called “telomeres.” Each time our cells divide, they must replicate their DNA so that each daughter cell gets a full set of operating instructions. However, … See more “Telomeres” are lengths of short, highly repetitive nucleotide sequences found on the ends of our DNA strands. Unlike the vital parts of our DNA, telomeres do not contain information needed to make proteins. Instead, … See more Telomerase has a core that is similar to the enzyme “reverse transcriptase,” also sometimes called “RNA transcriptase.” Reverse … See more 1. What is the primary function of telomerase? A. To add protective caps called “telomeres” to our DNA strands. B. To halt the aging process. C. To fight cancer. D.None of … See more The relationship of telomerase to cancer is not yet fully understood. This seems to be one case where the ancient philosophers who counseled “all … See more WebThe crucial role of telomeres in cell turnover and aging is highlighted by patients with 50% of normal telomerase levels resulting from a mutation in one of the telomerase genes. Short telomeres in such patients are implicated in a variety of disorders including dyskeratosis congenita, aplastic anemia, pulmonary fibrosis, and cancer.
