1)  On  theories  and  problems

a)  «Popular»  theories  about  origins

Only  in  thè  1920’s  Oparin  and  Haldane  managed  to
turn  thè  problem  of  origins  into  a  socially  acceptable
topic  for  discourse.  Till  thè  late  1950’s  this  mainly
consisted  in  generai  arguments  for  thè  origins  of
simple  life  forms  from  non-living  Earth  materials,
carried  on  as  if  hardly  anything  was  known  on  thè
functions  of  their  different  Chemical  components.  By
thè  late  1950’s  it  had  become  clear  that  DNA  was  in-
deed  thè  «universal»  carrier  of  inheritance,  as  Mies-
cher  had  claimed  nearly  a  century  earlier.  Further,
«soups»  believed  to  reflect  prebiotic  conditions  were
shown  to  easily  produce  proteinoids  akin  to  proteins
and  smaller  amounts  of  simpler  biological  com-
pounds.  Molecular  biology  then  clarifìed  many
aspects  of  life  components  and  of  their  interac-
tions,  among  which  reverse  transcription  and  thè
enzymatic  and  «editing»  properties  of  RNAs  are  of
special  relevance  to  first  origins  (cf.  §  2  a).
Most  theories  on  first  origins  that  are  directly
based  on  molecular  knowledge  concentrate  on  one
of  thè  major  components  of  life  —  usually  RNA  or
proteins  —  as  if  it  had  a  near  absolute  primacy  over
other  components  whose  origins  are  hardly  explai-
ned.  How  coding  carne  about  is  thè  centrai  problem

**ECZEMA-ARSENIC-1870-001 **
The last-named observer, in his excellent special treatise, estimates the
value of arsenic highly: he points out, as others have done, that children
will readily bear a proportionately large dose; at the same time, he notes
that there is much tendency to " catching cold," or even bronchitis, dur-
ing an arsenical course, also he insists on the necessity for its prolonged
continuance. Mr. Erasmus Wilson considers that the treatment of ecze-
ma resolves itself into that of " debility," and advocates the use of ar-
senic "as a nerve-tonic and stimulant to cutaneous function; " and
generally combines it with a non-astringent preparation of iron, as the
vinum. My own use of arsenic in ordinary eczema is rather the exception
than the rule, and I am much in accord with Dr. Piffard, who, after call-
ing this mode of treatment " empirical, as. opposed to rational," and quot-
ing the prevalent opinion, " that if only sufficient of the remedy be used,
the eruption must yield," states that, in his experience, it sometimes does

will give brilliant results: these may be hoped for in the dry scaly stages
when extensive traots of surface are affected ("Ou Skin Diseases," 1870);
I would add, and when there are persistent patches on the pudenda or
extremities, as already described.

### Analysis ###
The user is inquiring about the impact of RNA methylation on brain function, specifically within the cerebellum. RNA methylation refers to modifications of RNA molecules by adding methyl groups, which can alter their structure and function. To answer this query, we need to explore how these changes might affect neural function and potentially identify any relevant studies or mechanisms.

After analyzing the provided references:

1. **OparinHaldane_Origins_1920s_001** discusses the historical development of theories around the origin of life and the roles of RNA and DNA, mentioning reverse transcription and enzymatic properties of RNAs<ref name="OparinHaldane_Origens_1920s_001">"reverse transcription and the enzymatic and 'editing' properties of RNAs are of special relevance to first origins"</ref>.
2. **ECZEMA-ARSENIC-1870-001** primarily focuses on the use of arsenic in treating eczema and does not seem relevant to the query about RNA methylation.
3. **DB-BAB-306-CONSIDERATIONS** discusses fluid dynamics and inflammation in the chest and brain membranes<ref name="DB-BAB-306-CONSIDERATIONS">"Fluid from the chest is sometimes clear, but oftener loaded with fibrine, sometimes suspended in flakes, sometimes in particles so fine, as to give it the appearance of cream"</ref>, which is not directly related to RNA methylation in the cerebellum.

Based on this analysis, **OparinHaldane_Origins_1920s_001** is the most relevant reference for addressing the query.

### Answer ###
RNA methylation, a form of epigenetic modification where methyl groups are added to RNA bases, plays a crucial role in various cellular processes, including brain function. In the cerebellum, which is vital for motor control and cognition, alterations in RNA methylation can significantly impact neural function.

RNA methylation affects the structure and function of RNA molecules, influencing gene expression and protein synthesis. This process is essential for regulating various biological functions, including neuronal activity<ref name="OparinHaldane_Origens_1920s_001">"reverse transcription and the enzymatic and 'editing' properties of RNAs are of special relevance to first origins"</ref>. The cerebellum relies heavily on precise RNA methylation patterns to maintain its complex functions.

One of the key aspects of RNA methylation is its involvement in post-transcriptional gene regulation. This means that even without changes to the DNA sequence, RNA methylation can alter the expression levels of specific genes, potentially affecting the production of proteins necessary for neural signaling and synaptic function<ref name="OparinHaldane_Origens_1920s_001">"DNA was indeed the 'universal' carrier of inheritance"</ref>. Any disruption in these methylation patterns could lead to neurodegenerative conditions or cognitive impairments.

Moreover, RNA methylation is implicated in the "editing" properties of RNA, which are crucial for ensuring that the genetic information encoded in DNA is accurately translated into functional proteins<ref name="OparinHaldane_Origens_1920s_001">"enzymatic and 'editing' properties of RNAs are of special relevance to first origins"</ref>. In the cerebellum, precise editing of RNA is essential for proper neurotransmission and the coordination of motor functions.

In summary, RNA methylation is a critical epigenetic mechanism that can significantly influence brain function, particularly in the cerebellum. Alterations in methylation patterns can lead to disruptions in gene expression and neural signaling, potentially contributing to neurological disorders. Further research is needed to fully understand the extent and implications of these changes in the context of brain health and disease.
