comment Remove RNAse from pipettes?
I'd disassemble the pipettes and put the appropriate parts in DEPC solution. I would also consider other issues aside from RNAses, reduced yield can have many different causes.

comment How can cells produce antibodies despite error-checking mechanisms in their genomes?
This process is called somatic hypermutation. I just looked it up in my Alberts and it seems the exact mechanism is not known (though the book is a bit older now, this might have changed).

comment Ribosomal Turing Machines, DNA/RNA computation
There are some papers on simple computations using nucleic acids, if nobody answers I'll look them up later. As for your examples, nature already does some of them (see RNA interference). And for correcting genetic diseases, the hard part is actually correcting the sequence in all cells in your body, not the detection itself.

comment What I can do in order to improve the folding of the protein?
You'll have to add a lot more detail if you want to have a chance for any proper advice. All the known properties of the protein as well as your exact expression and purification protocols at minimum. Otherwise you'll only get some guesses and vague advice.

comment Local storage of NCBI database in MongoDB
@shigeta I usually put the line pretty far on the informatics side when deciding whether a question is off-topic, but this question is a bit far on the informatics side for me. The main question, how to convert an SQL database to MongoDB is better asked on a specialized site. But there is a question below that that might require some biology knowledge, and that is whether a NoSQL approach is useful for an SNP database.

comment How do penicillin resistant bacteria grow slower in the presence of penicillin?
You need to add a lot more detail for any answer to be possible. Which kind of bacteria were in there? Were they resistant to Penicillin. Did you work sterile?

comment What is the best file format to store gel images?
@terdon The lossless compression of PNGs still results in much larger images than JPEG. I personally use PNGs for almost everything, but there are situations where you need smaller files and where JPEG can be acceptable.

comment What is the best file format to store gel images?
@Chris I think the major issue here is not TeX-specific, it is more about good practices for documentation of scientific data.

comment Is there a correlation between brain size and amount of sleep?
I'm closing this question as it is cross-posted on CogSci already at cogsci.stackexchange.com/questions/6440/…

comment What information do microarray image convey?
In the general case the color simply indicates how much of a specific RNA or DNA is in your sample. What you get out of this depends heavily on the exact experiment you're performing.

comment What actually are the blood groups for human being?
I would have assumed that someone performing the blood test is typing in the information. I doubt anyone is relying on self-reported information for blood transfusion.

comment Do RNA molecules bind each other?
@golgicik 2'-OMe doesn't really affect base-pairing, it's a modification of the ribose.
