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.

Mar 4	revised	Serotonin - Does being aroused make you sleepy? edited body; edited title
Mar 4	comment	What makes a gene dominant or recessive Umm, on second thought, you are answering the question. Sorry, I really should learn not to comment just before going to bed. Comment removed and upvote added.
Mar 2	comment	Do repeated freeze-thaw strip nutrition from vegetables/food? Not as far as I know, they do however open the frozen foodstuffs to infection. It is not a good idea to thaw and refreeze for that reason.

Mar 2	revised	How does this diagram illustrate carbon cycling in lakes? some formatting
Mar 2	reviewed	Close A good textbook on Neuroscience
Mar 1	comment	Question about cell signaling pathways (RTK, Jak-Stat, SMAD, etc) Not sure what you mean. Notch has its own pathway, as does wnt and tgf-beta. Don't remember the other off the top of my head. Why don't you check them out on kegg?
Feb 27	comment	Why does Glutamine have the symbol Q? I know, it's just that I did my PhD on selenoproteins and everyone forgets selenocysteine and that makes me sad :(.
Feb 27	comment	Specific enzyme for C. elegans What level of similarity would be acceptable? What do you mean by "isn't common"? What exactly do you want to do?
Feb 27	comment	Why does Glutamine have the symbol Q? U is the code for selenocysteine.
Feb 25	comment	Can this theory on the evolution of human appearance be flawed? @OllyPrice your friend's entire argument is based on a wrong assumption. Offspring are not simply the average of their parents. Consider siblings, you can have a couple with 18 children, each of these will be different not simply the average of their parents. Mutation and cross over and simple errors in DNA replication ensure this.

Feb 22	comment	How does plant grafting work? I'll read the article and get back to you, thanks.
Feb 22	comment	How does plant grafting work? Wow, so you're teling me that the genes controlling fruiting are in the plastid genome?
Feb 21	comment	How does plant grafting work? @AlanBoyd, yes I imagine it is chimerism of some sort. Yet you can take a normal bitter orange tree, cut off most of its branches (not even sure that is necessary) and graft a piece of lemon tree bark onto it. From that day on, the entire tree produces lemons, not oranges. So, somehow the grafted tissue is suppressing the original plant. Not what happens in an organ transplant.

Feb 21	comment	Polymerase Observations Is this homework? What exactly are you asking?
Feb 21	comment	What are gram negative and positive bacteria? It is simply one of the major ways that bacteria are categorised. The cell wall will affect what drugs can kill them for example.
