Can mRNAs modify our DNA (publication misunderstanding)?
The short answer is maybe, but rarely, and the whole Covid virus has never been seen to integrate into the cell's DNA intact. Any integration requires "helper" molecules not found in the ...

Why is the new mRNA vaccine unable to modify human DNA?
Roman Zieliński seems to be intentionally misleading you by making an implausible circumstance that is technically possible sound like a likely outcome. This strategy is not unusual among people who ...

Is it possible to change person's blood group?
Yes, it is possible. In a bone marrow transplant, all of the patient's bone marrow is destroyed and replaced with donor marrow. Since red blood cells are created by bone marrow, the donor's blood type ...

Why is the new mRNA vaccine unable to modify human DNA?
To supplement Bryan's answer (although I'm not going to say anything fundamentally different here), according to their proponents, mRNA vaccines are considered the safest genetic vaccines (in this ...

Is the code from the mRNA vaccine executed by the cells as a one-off?
Basically neither of your hypotheses is correct. A piece of mRNA isn't usually destroyed after one transcription. Nor does it create an "infinite loop" in the cell. Instead there's a balance ...

Race and bone marrow donor search
What was once defined as 'scientific racism' is incompatible with what we know to be science or anthropology. Inter-group differences, supposed to be large in broad terms and used to qualify people, ...

Why do age-related DNA transcription errors not manifest in children as readily as their parents?
Older paternal (and maternal) age in fact is associated with some increase in disease, though at fairly low rates.
Cancer is largely a disease of probability. One does not need to have mutations in ...

Longterm effects on DNA of aciclovir
Aciclovir is a prodrug, which means that it has to be converted to an active form before having its desired effect.
It is converted to this active form (aciclovir triphosphate) by a

How to determine the chances of inheriting an autosomal recessive disease if the carrier status of parents is unknown?
Let's say that the families of partner 1 and partner 2 have no history of similar autosomal recessive disorders and we can therefor assume but not exclude (by natural mutation chance) they are not a ...

Decide parent and child from DNA
There is one case where you might be able to differentiate parent and child, taking advantage of the fact that mitochondrial DNA is only inherited from the mother.
If one genome is female and the ...

Is short exposure for a not high amount of radioactivity harmful? Has it benefits?
Nobody knows.
There are three main models for the effects of low-dose radiation. The mainstream model, and the most conservative of the three, is the linear no-threshold model. It assumes that high-...
