comment Is it possible for a human to wake up in a wrong way?
I think the "sleep inertia" you refer to is the reason - if you are woken by your alarm during a particular cycle of sleep this would have an effect lasting all day [haven't looked this up - anecdotal]. This would then be referred to as having woken up on the wrong side of the bed (which is just a saying not a literal reason why you are having an off day). Could be due to all sorts of reasons though, including nutrition, recent physical activity, stress, alcohol/drug consumption... etc!

comment Is using Hidden Markov Models to find homologues sensible in abstract, short sequences?
Hi there - seems like you may get an answer from someone on BioStars or another site with more computational/statistical expertise - as this question is not really biological per se, more bioinformatic

comment Obvious phenotypic inheritance markers in humans
Interesting question. Eye and hair colour (two "obvious" ones), to my knowledge, can be different from either parent due to the dominant/recessive nature of alleles. I would be interested to know of any "true" <trait characteristic>, as you put it

comment Can DNA & RNA be considered as nature's programming language?
Hi @a.aniq I have made some edits to your question, to give you an idea of how a question might be structured (i.e. remove anything subjective - clarified meaning); but there are still massive assumptions that you made that I have left in - if you do a little research to clarify your own understanding and substantiate some of your assumptions with sources this question may qualify for re-opening and one of us can provide you with a much more detailed answer :)

comment What software/approach to use to build a graph based on microarray gene expression correlation?
Hi @VassiaAlk - Cytoscape is pretty well designed for constructing a "network" of genes that are connected by their degree of correlation in expression; check out the online resources (e.g. apps.cytoscape.org/apps/expressioncorrelation). This site is aimed at biological questions, therefore this is off topic. Best

comment Genetic abscence of backpain among teen girls?
Hi & welcome to Bio.SE - this is an interesting observation! It is considered a requisite on this site that the poster includes some research themselves - could you include some links to posts or similar where you have read this? What are your thoughts? Thanks

comment Can DNA & RNA be considered as nature's programming language?
... there is more at work than simply the DNA. This field of regulation and differentiation concerns epigenetics, which are modifications to the DNA that do not change the genetic sequence, and is to some degree hertiable. Therefore it is incorrect to say that DNA alone makes an organism, and it is incorrect to say that other fields of biology are just beating around the bush - there are many more factors at play than just the genetic code.

comment Can DNA & RNA be considered as nature's programming language?
Was literally just writing an answer :/ in my eyes there is nothing opinion-based about this (although the question could be phrased better): classical molecular biologay says DNA makes RNA makes Protein. Whilst this is true, less than 2% of the genome is protein-coding, with the rest coding for regulatory regions and non-coding RNA molecules (often with important functions of their own). So whilst in some respects DNA could be considered the 'code' for organisms, it is much more complicated than this: each cell of an organisms has the same genetics but different phenotypes, so clearly ...

comment What are senescent cells doing in our bodies?
Voted to re-open. Although there are some misconceptions here this question is well within the realms of an overview answer of our current knowledge, in my opinion.

comment All UniprotIDs of a cancer pathway
@terdon good point about child terms being included as well in GO terms - I have voted up your answer as it seems more appropriate in this context!

comment What is it about the housekeeping genes that makes them almost immune to gene regulation?
Great answer - common misconception that "house keeping genes" are consistent in expression when used as reference genes. It is common practise to include several reference genes in many experiments and to confirm empirically that they do not vary between your samples.

comment Are codons that map to the same amino acids interchangeable?
Nice answer - I was considering posting another but it would be better if you just added this as another bullet point, as it is not mutually exclusive to your suggestions; this paper describes translational pausing of different lengths for different codons, even for the same amino acid, which affects protein 3D structure as well - so it would appear that codons in the DNA have another layer of information beyond that of simply saying which amino acid to add to the protein next!

Interesting point. No idea why cancers of the heart are so rare!

comment The damage of cancer cells
As you can see from the graph, it is not exact, but just a correlation between cell divisions and cancer - many other environmental factors affect cancer risk too, and some tissues may be more exposed than others? What makes you say muscle specifically?

No problem @MalicOfSdom. If I have answered your question please accept it. If you would rather wait to see whether others answer as well feel free, but vote up/down as appropriate, and accept an answer to help future users of this Q&A !

comment Does increased cell turnover cause cancerous mutations?
So is your question "Does increased replication rate lead to a higher likelihood of mutation?"

comment Parallels between pixelized image and the human retina
Interesting answer. In the field of view do the photoreceptors each connect to a single nerve? Roughly speaking how many photoreceptors may channel into a single nerve fiber, on average (unless there are actual values for different areas of the eye!)? This would ultimately be the smallest "resolution" or "pixel size" then, rather than the size of the photoreceptor itself. Thanks again
