I can't unequivocally say, at least without further literature review, that both sister chromatids are transcribed equally everywhere, especially since the cell does have mechanisms to differentiate between the old and new DNA strands (such as methylation state). It would be conceivable to expect, however, that the same regulatory factors that were present ...


21joanna12, look into snRNPs. These are parts of the splicosomal apparatus and some of them (the U1 and U2, U11 and U12 snRNPs) are also the guideposts that bind near the splice junctions at the end of introns. These help guide the splicing apparatus to the splice sites. There are also proteins that bind RNA and interact with the splicing apparatus to ...
