Telomerase is found in fetal tissues, adult germ cells, and also tumor cells. Telomerase activity is regulated during development and has a very low, almost undetectable activity in somatic (body) cells. Because these somatic cells do not regularly use telomerase, they age.
You are observing the metaphase phase of mitosis
Mitosis is a process of cell reproduction in which a cell divides to produce two daughter cells that are genetically identical to the parent. Metaphase is the third phase of mitosis. During this phase, the two centrosomes pulls the chromosomes towards the opposite poles of the cell which causes the sister chromatids to line up neatly across the middle (equator) of the cell.
