MEDICAL UTILITY
These researches are very
important in my opinion because of
the clinical application:
The first one talks about
investigating the telomeres and
understanding these complex
structures may help future medicine
with new treatments for diseases
like cancer.
The second one
Dr. Sousa thinks this new method to
make RNA molecules that are
chemically diverse will speed up
research exponentially.
In my humble opinion Dr. Sousa is
too optimistic but, if he is right,
biological sciences will benefit
most.
Until now make RNAs to develop
diagnostics and therapeutics has
been limited by existing technology.
The interest in this is because RNAs
are molecules that can be used to
make therapeutics, sensors and
diagnostics.

3. Defective telomeres are now
being linked to dozens of
diseases, including many types
of cancer:
Telomeres are the structures that
prevent the DNA strands makes
chemically bonds to other strands,
i.e. the chromosomes would merge
and that would be lethal for the
cell.
The researchers are amazed about
how complex is the biology of
telomeres, and the high number
of factors “they are finding that are
essential to the preservation of
telomeres and, above all, the
precise coordination that is
required between them all.”
STUDENT OBSERVATION
In my opinion what they are
investigating is very important and
will be will be a key issue in the
future research, because they talk
about topics of great interest for
modern science like are cancer
therapy and ageing.
INTRODUTION
In recent years not only their
relation to ageing has been
confirmed; also defective telomeres
seem to be linked to a lot of diseases
even with some types of cancer, this
is very important for the future
medicine. The importance of
investigating these structures is to
improve diagnoses and develop
possible treatments for many
diseases. Telomeres, in the opinion
of these researchers, will become
increasingly important in clinical
studies.
Different types of RNAs perform
different functions, such as silencing
a gene or regulating a plethora of
processes in cells.
The new method described by Dr.
Sousa and his colleagues in Nature,
which includes robotics, will speed
up research exponentially.
This is desirable for studies of RNA
structure and function, and for
design of applications that could be
used to diagnose and treat diseases.
This new technique allows the
researcher make RNA molecules
that are chemically diverse.
Revolutionary method of making
RNAs:
Rui Sousa, Ph.D., professor of
biochemistry in the School of Medicine at
the Health Science Center is a co-author
on the paper with colleagues from the
National Institutes of Health, the
University of Colorado, said that “RNAs
are molecules that can be used to make
therapeutics, sensors and diagnostics, for
which there is a growing market”.
He and his colleagues describes a new,
more efficient method of making
ribonucleic acids (RNAs).
"This new technique allows a
researcher to make RNA molecules that
are chemically diverse,“ and they think
this new method, will speed up
research exponentially.
STUDENT OBSERVATION
Dr. Sousa and his collages propose a
new method for making RNA in a
more effective way, that will help a
lot in my opinion because of what the
told us at the beginning “RNAs are
molecules that can be used to make
therapeutics, sensors and
diagnostics“.

6. TELOMESRES
Telomeres are the ending
regions of a chromatid, their
presence protects the genes
before them on the
chromosome from being
truncated instead.
Defectivetelomeres arenowbeing linkedto dozensofdiseases,including manytypesof
cancer:

7. Theresearchersinvestigate telomeres, this
structuresare being linkedto diseases like
cancer, this show us the great importance of
telomeres and their function in the prevalence
of the chromosome structure.

8. telomeres havebeen tightly preserved
throughout the evolution in all cell lines,
that indicates its importance.
Theyprevent the fusion of chromosomes
and the loss of genetic information each
time a cell divides.
