Alternative Splicing Goes Mainstream
Sam Jaffe | Dec 14, 2003 | 10 min read
In eukaryotic genetics, the one-gene/one-protein concept has, for the most part, breathed its last. Researchers have rallied behind mechanisms such as alternative splicing, which may allow a lowly 30,000-gene genome to produce the dizzying variety of proteins that some believe is necessary to produce beings as complex as humans. Alternative splicing--the post-transcriptional editing process that can result in various mRNAs--was previously seen as an interesting but relatively uncommon sidesh
