| 31. | Telomeres appear to be a kind of cellular clock.
|
| 32. | Every time a cell divides, it loses a little of its telomeres.
|
| 33. | After telomerase manufactures telomeres, it is switched off.
|
| 34. | Weinberg suggested that everyone might have enough telomeres to live to be 200.
|
| 35. | The shortening of the telomeres is the mechanism that underlies the Hayflick limit.
|
| 36. | Telomeres are kept long in egg and sperm cells by the enzyme telomerase.
|
| 37. | Cells with longer telomeres can divide more often and live longer than normal.
|
| 38. | Telomeres form large loop structures called telomere loops, or T-loops.
|
| 39. | Telomeres form large loop structures called telomere loops, or T-loops.
|
| 40. | Telomere shortening in humans can induce replicative senescence, which blocks cell division.
