I do not have enough context from the given text to determine what "her mother had said to her, see, they have a beautiful life" is referring to. The excerpt does not provide any other details about the characters or situation.

1. Central dogma of
genetical information.
BY ADOLFO ZULUAGA.
THIRD SEMESTER.

4. Introduction
History.
The dogma was established by Francis Crick in 1956, he postulated: “ It states
that such information can not be transferred back from protein to either
protein or nucleic acid” and that principle is still valid nowadays.
Then, in the 80’s, S. Brenner, F. Jacob and Matthew Meselson discovered the
RNAm.
Process.
The process consist in two parts, The nucleus’s part: replication, and
transcription from DNA to RNA, and the cytoplasm’s one: Translation from RNA
to protein.
Prions
The prions are infectious proteins that act like genes, so they are able to
replicate and transmit information, using inverse transcription. Their origin is
from chromosome 20.

5. ProMIS Neurosciences announces
new program to identify novel
Alzheimer's disease targets on toxic
strains of protein Tau.(July 14,
2016)

6. ProMIS Neurosciences
announces new program to
identify novel Alzheimer's
disease targets on toxic strains
of protein Tau.
The damage of Tau protein causes a
neurodegenerative disease because the
protein stabilizes microtubules, present in
axons of neurons of SNC, astrocytes and
oligodendrocytes.
Tau protein is the product of a gene located
in chromosome 17.

7. ProMIS Neurosciences announces
new program to identify novel
Alzheimer's disease targets on
toxic strains of protein Tau.
So… what the investigators wanted to do?
They wanted to study the Tau protein and not
β Amyloid protein, due to Tau is less studied
than the amyloid one, so they could develop a
new perspective of the disease.

8. ProMIS Neurosciences announces new
program to identify novel Alzheimer's
disease targets on toxic strains of
protein Tau.
As I have already said, they
investigators also wanted to study a
treatment to the Alzheimer’s disease,
finding folding proteins inside of Tau
proteins and that’s why the used the
prions for this cause, to solve the
aggregates and stop the illness.

9. Student’s comment.
I have said that the importance of researching the
treatment and a easier easy to diagnosis and treat
this pathology along the folding and the
presentation, but now I would like to say that even
and unfortunately I have no related siblings with
this disease, but my aunt’s husband has a kind of
dementia and I can say it’s very difficult to his
family and his daughter, now that he can´t
remember them sometimes and maybe there is
not cure for him, with investigations his daughter
would prevent the pathology and get a genetic
treatment.

10. Copper-induced misfolding
of prion proteins (July 1,
2016)

11. Copper-induced misfolding of
prion proteins
Copper is in our daily diet, it is important to form
red blood cells, keep up the blood vessels, the
nervous system, bones in combination with iron.
Low concentrations in plasm are related with
anemia and (osteoporosis), and the high ones, with
Wilson disease and hepatitis.

12. Copper-induced misfolding of
prion proteins
Copper ions can misfold proteins and seed the
misfolding and clumpling of prion proteins accused of
inflammation and damage to nerve cells.
They targeted prion proteins to discover a signal of
neurotoxicity caused by copper, but at the end, an
author concluded that “There are different strains of
misfolded prion proteins and not all of them are
pathogenic.”
It is also important to know, that prion proteins are
affined to copper ions and that’s why they used in the
experiment.

13. Copper-induced misfolding of
prion proteins
The copper ions are available to detonate neurotoxicity
and cause the disease. But… How?
Copper transforms the prion proteins (that stabilize the
cytoskeleton of neuron) and cause the degeneration the
nerve tissues, basically, copper activates the neurotoxicity.

14. Student’s comment.
First able, the main importance of the results, is the
relation between copper ions and neurodegenerative
diseases, that’s because of the abnormal prion
proteins made by copper ions.
Copper is present in nuts, beans… food that is usually
consumed, so this study provides a prevention of high
levels of this kind of food in our diet.

15. Medical importance.

16. Medical importance.
The prions are pathogenic agents that
cause encephalopathy and neurotoxicity,
prions can spread into their host, but their
difference with viruses resides on their
resistance of nucleic acids treatment and
the fact that they can replicate and pass
on a disease without involve nucleic
acids.

17. Medical importance.
As I’ve said, the prions act like genes, so they can disturb
the cell, in this case, the neuron, those mentioned
experiments try to understand the process of intoxication
and damage of the neuron and determinate a treatment
or way to save the patient of the neurodegenerative
diseases.

18. Medical importance.
The main conclusion of those researches are the
possibility of the total cure of many diseases that
have not one at the moment and the knowledge of
how a pathogenic protein or an ion can cause
destruction of neuronal tissues and cause those
states of dementia.
