'Megapixel' DNA Replication Technology Promises Faster, More Precise Diagnostics
•The new digital polymerase
chain reaction (PCR) device
uses liquid surface tension,
rather than systems of
microscopic valves, to
partition DNA samples into
arrays of 1,000,000 chambers
or more. The device enables
the direct counting of single
molecules isolated in
individual chambers.

'Megapixel' DNA Replication Technology Promises Faster,
More Precise Diagnostics• PCR is an indispensable molecular
biology technique used by
researchers to amplify or copy a
single piece of DNA millions or
billions of times.
• The technique is about repeated
cycles of heating and cooling of
the reaction to replicate segments
of DNA using a protein called DNA
polymerase.

'Megapixel' DNA Replication Technology Promises Faster,
More Precise Diagnostics• This new generation of DNA replication
technique increase the sensibility and
density more than the original technique.
• It has the capacity to identify mistakes
sequences between two little target until
by a single nucleotide variation.
• The new 'megapixel' technique set new
benchmarks in detecting rare mutations.

'Megapixel' DNA Replication Technology Promises Faster,
More Precise Diagnostics• That new discoveries is an
opportunity to diagnosis any
pathology earlier and
beginning the treatment with
more opportunities to grow up
without any genetic disease
and this approach are so
important to for the science
and improve at the new
investigators to continue with
the legacy.

NITROGENOUS BASES OF DNA AND RNA
![Page 11: FOLDING](https://reader035.vdocuments.mx/reader035/viewer/2022070321/558e6e381a28ab084a8b4597/html5/thumbnails/11.jpg)
Researchers Identify Seventh and Eighth Bases of DNA
• Those four bases have been
taken in books about science
and have formed the basis of
the growing knowledge about
how genes code for life.
• Scientists have expanded that
list from four to six.
![Page 12: FOLDING](https://reader035.vdocuments.mx/reader035/viewer/2022070321/558e6e381a28ab084a8b4597/html5/thumbnails/12.jpg)
Researchers Identify Seventh and Eighth Bases of DNA
• These last two bases called 5-
formylcytosine and 5
carboxylcytosine.
• That have been modified by Tet
proteins, molecular entities that
it function is in DNA
demethylation and stem cell
reprogramming.
• This methylation is associated
with gene silencing.

Researchers Identify Seventh and Eighth Bases of DNA
• The discovery could advance stem cell research into the
DNA changes such as the removal of chemical groups
through demethylation that could reprogram adult cells to
make them act like stem cells.
![Page 14: FOLDING](https://reader035.vdocuments.mx/reader035/viewer/2022070321/558e6e381a28ab084a8b4597/html5/thumbnails/14.jpg)
Researchers Identify Seventh and Eighth Bases of DNA
• This approach are to effective to
“return“ this person to health state.
Those new bases are so important
and are involves in diseases process
like cancer, and could be an
advanced to genetics studies because
that found could provide new tools to
erase previous methylation patterns
to reprogram adult cells.

EARLIER DIAGNOSIS
![Page 16: FOLDING](https://reader035.vdocuments.mx/reader035/viewer/2022070321/558e6e381a28ab084a8b4597/html5/thumbnails/16.jpg)
MEDICAL UTILITY• This discovery could have
important implications for
stem cell research, and it
could provide researchers with
new tools to erase previous
methylation patterns to
reprogram adult cells.
• It could also inform cancer
research, and it could give
scientists the opportunity to
reactivate tumor suppressor
genes that had been silenced
by DNA methylation.

MEDICAL UTILITY
• It could has more of precision
in measurements in
biomedical research and
diagnostics.
• The PCR it could be
transformed in routine exam
and analytical tool because is
a more economical tool, that
is that everyone hopes.

•Those advances are so important to any
camps like medicine, molecular biology
and genetics.
•There are important tools to earlier
diagnosis of many important pathologies,
that could be unrehab if it haven´t has
that diagnosis.
