CELLULAR CYCLEBy: Juan José Garcés Ortiz
2015 Third semestre
Cell Cycle is a very importan process in which cell are able to self- reproduce and preserve their genetic material
The Cell Cycle is composed by 5 phases, G1,S,G2,Mitosis and G0
SMALL SIGNALING MOLECULES GIVES GREEN LIGHT FOR CELL DIVISION

SMALL SIGNALING MOLECULES GIVES GREEN LIGHT FOR CELL DIVISION
1. c-di-GMP controls the cell cycle in a similar way as a traffic
light works. In the absence of c-di-GMP in the cell, the light shows red. This indicates that the cell will have to remain in
the first phase of the cell cycle.

If the c-di-GMP level increases, the light
switches to green and the cell enters the
next phase.

However, as soon as c-di-GMP is produced, it binds to the enzyme,
thus altering its structure and mode of action. Subsequently, this
blockade is lifted and the bacterial chromosome can be copied.

I think this is important because, they are many thing´s that are still a mystery, regarding all this process , and discovering this new molecules will help us reach the goal of understanding this whole process
How dividing cells end up the same size.

How dividing cells end up the same size
This finding goes against recent publications
suggesting cells always add the same amount of mass, with some random
fluctuations, before beginning division.
How dividing cells end up the same size
The team was looking at how genes on circular pieces of DNA called
plasmids segregate when cells divide by tagging the
genes with different fluorescent colors.
How dividing cells end up the same size
The setup allows researchers to watch hundreds of cells go
through divisions over dozens of generations and was key in seeing
the baffling oscillations.

Student Opinion
This investigation is import because will help us, in a better understanding of
the cell reproductive system and how mom
cells, are a main fact for future studies.
MEDICAL UTILITY
Medical Utility
These studies represent a good advance to reveal
new data, about the process of cell
reproduction, that may be used for future studies
of their main related pathology, the cancer.
Medical Utility
Discovering new molecules that are
involved in the process is very important
because, ass better we know the mechanism ,
we will be able to repair it and make it better.
Medical Utility
Most of the cancer start during the cell cycle, and the
oportunity to repair this is by studying this process and keep discovering new information, that will lead us to the cure.
