WebMar 31, 2024 · Two genes from the family encoding mouse ribosomal protein S16 were cloned, sequenced, and analyzed. One gene was found to be a processed pseudogene, i.e., a nonfunctional gene presumably derived from an mRNA intermediate. The other S16 gene contained introns and had exonic sequences identical to those of a cloned S16 cDNA. WebX-inactivation is a random process that happens separately in individual cells during embryonic development. One cell might shut down the paternal X, while its next-door neighbor might shut down the maternal X instead. All the cells descended from each of these original cells will maintain the same pattern of X-inactivation.
