Activation of cryptic 3' splice sites within introns of cellular genes following gene entrapment.

abstract：:We have developed an end-labelling approach to map the positions of nucleosomes and protein binding sites at nucleotide resolution by footprinting micrococcal nuclease (MNase)-sensitive sites. Using this approach we determined that the MFA2 gene and its upstream control regions have four positioned nucleosomes when tr...

Two key processing steps include a precise cleavage within the 3' end of the pre-mRNA, and the subsequent polymerization of adenosines to produce the poly(A) tail. In yeast, these two functions are performed ...
