comment Regulation of chromatin structure
AFAIK chromatin would not assume the most compact structure without topoisomerase activity.

I didn't downvote your answer, I'm not really in much of a position to judge it, but it does seem to be unnecessarily complicated.

I know yeast is supposed to have very little non-coding DNA, but could it be possible that mitochondria in yeast have more intron regions?

comment Mitosis in human body
That's right, but they do develop from precursor cells that contain a nucleus. To be honest, I don't know of many other cells that continue dividing at a steady rate. As far as I know cells such as fibroblasts and macrophages are mainly produced in response to stimulus. There are probably other types that I am missing however...

That's right. I was wondering if the images could be superimposed somehow, since that was not very clear to me.

comment Can protein structure be determined by X-Ray Diffraction in a single image?
Thanks for your answer. I didn't mention it in my question, but my book does say that a vast number of crystalised proteins are required, and that simultaneous diffraction amplifies the signal. What I was trying to ask is if a type of crystalised protein conformation can be determined from a single image or if many different images would need to be produced for each angle of rotation. From your answer it sounds as if all the information required is stored on one image - is this correct?

comment How does water buffer a sudden drop in temperature?
I know this is probably more a physics question, but I think it is related to biology. If someone would like to move the question, then feel free to. I have edited it so hopefully my question makes more sense now.
