Saltillo Violence: Mother Killed With Daughter, Baby Found With Bodies, 3 Sicarios Killed. in Coahuila, from Torreon (la Laguna) east to Saltillo, north to Piedras and AcuÃ±a, the once relatively peaceful state seems to have become the stage of violence and crime. Above is Perla she is the mother of the baby.
Splice site mutation. A splice site mutation is a genetic mutation that inserts, deletes or changes a number of nucleotides in the specific site at which splicing takes place during the processing of precursor messenger RNA into mature messenger RNA.
Most splicing occurs between exons on a single RNA transcript, but occasionally trans-splicing occurs, in which exons on different pre-mRNAs are ligated together. The splicing process occurs in cellular machines called spliceosomes, in which the snRNPs are found along with additional proteins.igure 1: Pre-mRNA splicing. Splicing of a pre-mRNA molecule occurs in several steps that are catalyzed by small nuclear ribonucleoproteins (snRNPs). After the U1 snRNP binds to the 5â² splice site, the 5â² end of the intron base pairs with the downstream branch sequence, forming a lariat.
