4. 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

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.

Student opinion.Student opinion.
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

10. How dividing cells end up the
same size.

11. How dividing cells end up the sameHow dividing cells end up the same
sizesize
This finding goes against
recent publications
suggesting cells always
add the same amount of
mass, with some random
fluctuations, before
beginning division.

12. How dividing cells end up the sameHow dividing cells end up the same
sizesize
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.

13. How dividing cells end up the sameHow dividing cells end up the same
sizesize
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.

16. Medical UtilityMedical 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.

17. Medical UtilityMedical 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.

18. Medical UtilityMedical 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.
