Roche has put forward a new approach to genetic analysis, which it describes as sequencing-by-expansion—a proprietary method that pulls apart the DNA molecule and amplifies the signal of | Roche said ...

RNA splicing is a cellular process that is critical for gene expression. After genes are copied from DNA into messenger RNA, portions of the RNA that don't code for proteins, called introns, are cut ...

Biologists have discovered a new type of RNA-splicing regulation that helps to determine which protein-coding exons will be included in messenger RNA transcripts.
