Elected moderator on Unix & Linux. Feel free to @ping me in chat if there's anything I can help you with.

I am a computational biologist with a background in biology, not computers. My PhD work was on gene prediction and comparative genomics but my current research is in systems biology, specifically protein-protein interaction networks.

comment Hidden Markov Model
<this is about to get closed. I think it could be on topic if you edit it to make it specifically about the applications of HMMs to biology. For example in gene prediction or in the building of sequence profiles (e.g. hmmer)

comment Looking for a DNA sequence
@www.sapnaedu.in please explain what you are actually trying to do. There are hundreds or thousands of available cancer datasets but which one is good for you will depend on the analysis you will perform. Most sequences will be identical in cancer and healthy tissue. If you want to find patterns characteristic of cancer you will need to be more specific.

comment Looking for a DNA sequence
@www.sapnaedu.in huh? What pattern? You don't mention anything like that in your question. The sequences you are using are not from cancer, do you want sequences from cancer patients?

comment Visualisation of phylogeography
You might want to consider asking this question on biostars.org as well. Just to be clear, it is completely on topic and welcome to stay here, but you could also ask it on biostars.

comment parallels or replicates?
In any case, parallels won't work, you want experiments run in parallel which is not the same thing. Parallels cannot be used that way.

comment Can cancer be an immune system disorder?
Yes, too broad and also too basic. We expect users to do research before asking, a cursory reading of the 1st paragraph of wikipedia's entry on cancer would show you that it is "a broad group of diseases involving unregulated cell growth" and not an immune disorder.

comment Can cancer be an immune system disorder?
This question appears to be off-topic because it is a wild stab in the dark with no research or any indication of why the OP might believe this to be the case.

comment Can cancer be an immune system disorder?
Please try and do some research before posting. At least explain why you think that cancer would be an immune disorder. As it stands, your question is like asking whether McDonald's makes cars. Unless you give some reason why you think it might be a car maker, the question makes very little sense.

comment What is the creature with the lowest neuron count that demonstrates cognition beyond reflexes?
How would you demonstrate that human cognition cannot be boiled down to scripted actions? Your question seems to assume its answer.

@user13107 yes, that's why I used it.

comment How do we know that everybody's DNA fingerprint is unique?
Yes, the fact that they are highly variable. I don't have the numbers at hand but while it is theoretically possible for two DNA fingerprints to be identical, I would expect a similar or smaller probability of this than for "real" (let's call them digital) fingerprints.

comment Does antibacterial soap work chemically?
How does "waiting a minute or two" as opposed to "scrubbing for a minute or two" change the time it will take you to shower? How long do you scrub for? Why in the world do you shower using antibacterial soap? Depending on the soap that can be dangerous and is almost certainly unnecessary and very likely counter productive.
