Using the diagram on the left, what happens to the telomeres every tim the cell divides? What happens to the cell if there are no more telomeres? Comparing the diagram above for a normal cell to what you know abou the rate of growth in cancer cells, how do you think telomeres in cancen cells differ from normal cells? What would any potential advantages and/or disadvantages be if scient could alter the amount of telomeres we contained on our chromosomes

Question
A "telomere" is a substance has no apparent reason for existing except to
provide a kind of "blank leader" that protects the vital DNA code each time
it makes a copy of itself. The amount of times the DNA in a normal cell can
reproduce before this vital telomere is worn away is called the Hayflick
limit.
Using the diagram on the left, what happens to the telomeres every time
the cell divides?

What happens to the cell if there are no more telomeres?
Comparing the diagram above for a normal cell to what you know about
the rate of growth in cancer cells, how do you think telomeres in cancer
cells differ from normal cells?
What would any potential advantages and/or disadvantages be if scientists
could alter the amount of telomeres we contained on our chromosomes?
