This passage overwhelmed me, but reading it again, I realize that it is just describing a pretty straightforward cascade. Unfortunately, under timed conditions and when I'm not feeling the best/over anxious, I tend to flip out and rush/mess things up.
However, in regards to this question, what are "nuclear factors"? Does that mean transcription factors? I don't really know a lot about this topic; I guess this question required that you know what transcriptional machinery was not constant from cell to cell.
So does this mean that every cell in the body contains any type of gene, promoter, or enhancer? Why would a gene related to growth of your toenail be located in your eye (not kidding)?
This might sound like a stupid question, but I'm being honest.
Are all genes in the body located in every cell? They just remain inactive in some cells?
So if we took the transcription factors for the growth of your fingers and transferred them into cardiac cells, your heart would be capable of growing fingers?
