What is the advantage or disadvantage that people used telomere?
I'm sure the best answer is in the article you were assigned to read.
can you please answer my other questions?
Telomeres are repetitive DNA sequences located at the ends of chromosomes that protect them from degradation and fusion with other chromosomes. The advantage of telomeres is that they play a crucial role in maintaining the integrity and stability of the genetic material throughout cell division. They act as protective caps, preventing the loss of essential genetic information during DNA replication.
One advantage of telomeres is that they allow cells to divide multiple times without significant damage to the genetic material. This is particularly important for cells that need to replicate regularly, such as stem cells and immune system cells. Telomeres ensure that the genetic information is accurately copied and passed on to daughter cells.
On the other hand, a major disadvantage associated with telomeres is their gradual shortening during each cell division. This shortening is a normal part of the aging process. Eventually, when telomeres become critically short, they can trigger a cellular process called senescence, which leads to cell cycle arrest and limits the cell's ability to divide further. This is seen as a contributing factor to the aging process and age-related diseases.
In the field of research and medicine, understanding telomeres has opened up avenues for exploring various potential applications. Scientists are investigating ways to manipulate telomeres to extend the lifespan of cells, potentially slowing down aging and age-related diseases. However, it is important to note that tampering with telomeres is a complex and evolving field, and extensive research is still needed to fully understand the benefits and drawbacks of such interventions.
