comment Why do I smell chlorine when my sinuses are clogged?
@DonLarynx no, I meant ionic. Chloride ion does not covalently bond to water.

comment Why do I smell chlorine when my sinuses are clogged?
There is a big difference between chlorine gas $Cl_2$ and chloride ion $Cl^{-1}$. In physiological systems, chloride is ionically bound to the protic end of $H_2O$ in solution. It cannot spontaneously bond with another chloride ion to form $Cl_2$. So, the "chlorine smell" you are experiencing likely has absolutely nothing to do with $Na^+/Cl^-$ ion channels.

@Rishika No, the proteome.

comment Specific genetic code sequence
I don't understand this question, or the point of it. You just want any old mRNA sequence between 100 and 1000 bases? Why? NCBI is full of sequences (see @canadianer's link above), why couldn't you just look there?

comment Coffee efficiency?
That's fine amongst friends, but as a new member of a community you may want to tread more lightly until you're familiar with how things work, and have developed some relationships. I am absolutely not ashamed whatsoever that I'm a scientist, and I often refer to myself as a nerd or geek. However, addressing strangers like that is rather different.

Hint: When asking for help with something, it's probably best to not insult the people you are asking.

comment 16S rRNA sequencing
Have you done any research at all? Google would be a great place to start.

comment Inoculation vs. vaccination
Cowpox (Vaccinia) is not "weakened smallpox" (Variola). They are entirely separate, but related, viruses.

Practically all social groups have hierarchies. Why shouldn't cows?

comment Were we able to create vitamin B12 in past?
Bacteria (and archaea) produce B12, not mammals. Full stop. It is absorbed into the host's body, and passed along when those hosts are consumed by other animals, including humans. The difference between self-production and symbiosis is the point. You claim that herbivores produce B12 by themselves, and that is simply not true, any more than saying humans produce iron because it is found in our hemoglobin is true. Animals have never been B12 producers, because we lack the necessary biochemical pathways.

comment Were we able to create vitamin B12 in past?
from the very first sentence of the section you link to: "Ultimately, animals must obtain vitamin B12 directly or indirectly from bacteria...". Therefore, herbivores don't produce B12 themselves - it comes from bacteria in their gut. I don't understand what your statement about cows and flies means...

comment RF Cautery DNA damage?
@AlBundy interesting that the page you linked to doesn't indicate where the study was published. Anybody can run a study and publish on the internet, citations and all, but unless it's peer-reviewed and approved by a group of independent scientists in the field, it's meaningless.

Excellent response. I especially like the knife vs. belt sander example :)

Have you done any research? There are lots of resources out there. If you have a specific question, please edit your question and narrow it down.
