Telomeres and telomerase serve to give information about age and pathologies like cancer.
Cell division is a important process to give rise to new
cells containing their complete genomas.

Using biochemical and genetic assays the protein Lem4 is structurally different in human cells and embryos of the worm, but have the same function in cell division.

Lem4 is a protein which simultaneously co-ordinates the activity of kinases and phosphatases on a target protein essential for cell division.

It is essential that the nuclear envelope disappears during cell division and then reassemble it correctly, to occur this is necessary for the participation of kinases and phosphatases proteins.

OBSERVATION
In this study we can observe the importance of phosphorylation and desphosphorylation reactions and its essential role in cell division and cell operation.

Telomerases protect chromosomes from deteriorating and guard the genetic information at the ends of chromosomes during cell division. Besides’ they are considered markers of biological or cellular aging.

Shortened telomeres have been linked to increased risk of cancers, heart disease, dementia and mortality.

The length of telomeres depends on the stress, worries and phobias.

OBSERVATION
I think anxienty and stress are emotional feeling that people can control, because these affect cromosomes in the telomeres and reduce life average.

The DNA structure is very important because it has the information about each personal genome, this study has to protect the life and the personal safety and the culture of the people because al cientific investigation has to be ethics.

Knowledge of the nuclear envelope met know different molecules involved in cell cycle and that way related pathologies such as cancer.
