This question is addressed both to those researchers who only read already-written opinions and to those ones who “look before and after“, having in their mind the thoughts still virgin for everybody's reading. It is necessary to take into consideration that the living cells are located in a media (super-cytoplasm) that contains all essential ingredients.
Finding of the professional answer to this question is of importance by no means for understanding the problems of parasitology only but also for understanding the species diversity and a number of related subjects. If the origin of new DNAs is possible, this, apparently, means that formation of foreign cells and living issues is also possible.
A start of discussion about a related question is available by the address: https://www.researchgate.net/post/A_funny_question_bacteria_in_the_brain_do_they_migrate_thereto_or_originate_therein
There is a difference between "possible" and "probable". Scientists should very very rarely say anything is "impossible", but we might say the probability is less than one in sixty trillion or something like that. We also may speak of what evidence we have for or against a certain theory.
It is rare but not unheard of for eukaryotic cells to take in foreign DNA. DNA that can be replicated by the cellular machinery once it enters the cells is rare but not unheard of. DNA that is truly self-replicating once it enters a cell is very very rare outside of the true viruses and bacteria.
Dear Brian Thomas,
Thank you.
Your answer is of interest but it contains one inaccuracy. Most researchers are sure that the possibility or impossibility of any process is determined by thermodynamics but not only by kinetic or mechanistic laws. And scientists by no means rarely are capable of concluding that some process is impossible and by no means rarely make this.
But I understand that not this is important in your interesting answer.
Indeed, each cell is born by the maternal cell and inherits initially a half of its content. I write about a hypothetic possibility of the birth of new DNAs in the intercellular protoplasm with the subsequent formation of organophosphorous capsule and more or less usual organelles, similarly to the birth of the first living issues as it is described in our works on the process of living matter origination (for example,
Chapter Mitosis and DNA Replication and Life Origination Hydrate Hyp...
andArticle Life Origination Hydrate Theory (LOH-Theory) and the Explana...
.
I think applying and clearing the questions below can make it easier to understand and more interesting discussion.
Which type of molecules are the first origin of life? proteins? RNAs? DNAs?
Which of those are the brain of a cell? (do you believe cells are intelligent? )
...
Dear Alireza,
It would be better if you could read at least one of our last detailed papers on this not simple subject, for example,
Article Life Origination Hydrate Theory (LOH-Theory) and the Explana...
In short, the periods of living-matter origination occurred repeatedly, proceeded in different methane-hydrate localizations, each process from minerals to living issues, beginning from N-bases, nucleosides, nucleotides, DNAs and RNAs, cells and their differentiation into plants and animals, etc., proceeded in any one methane-hydrate localization as a result of diffusion of nitrate- and phosphate-ions into it, the reactions began within the solid methane-hydrate localizations and continued, after their liquation, within the structured supercytoplasm; it is shown that all processes are thermodynamically possible and kinetically provided. Complicated organisms resulted from symbiotic reactions, which began within the same supercytoplasm, etc. We also formulated the Mitosis and Replication Hydrate Theory (MRH-Theory) on the basis of similar principles; it is available, for example, by the addresses:
Chapter Mitosis and DNA Replication and Life Origination Hydrate Hyp...
andArticle Life Origination Hydrate Hypothesis (LOH-Hypothesis): Origin...
.With no details, according to the theories, the cells originated in concentrated and structured cytoplasm through formation of DNAs and formation of envelopes around them.
Regards.
Dear Victor Ostrovskii
I studied exactly this par you mentioned and my question is:
even a stable DNA created, proteins that do translate for example comes from?
Dear Alireza,
Yes, we didn't forget about proteins, see:
Article Life Origination Hydrate Theory (LOH-Theory): Thermodynamic ...
Yes, DNAs were also created.
Regards.
Dear Dr. Brian Thomas Foley,
Judging by your issues, I believe that you are an expert in parasitology, and I regret that you vanished after my issue about unproved impossibility of origination of foreign DNAs and foreign cells under some conditions in the intercellular cytoplasm. Meanwhile, as I believe, this question is not idle and its positive solution could explain a number of unexplained phenomena occurring in organisms. Maybe, you agree that sometime and somewhere the primary living issues originated, nevertheless, within some natural super-cytoplasm.
I do not think it is possible to multiply the parasitic DNA of the parasite because the parasites do not have the potential to multiply in the viruses
