Although heart cells and skin cells contain identical instructions for creating proteins encoded in their DNA, they're able to fill such disparate niches because molecular machinery can cut out and ...

When a gene is expressed, its DNA sequence is transcribed into a molecule known as RNA. Then the cell processes and edits that RNA before it is translated into protein. Many genes can be processed and ...

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. RNA splicing is a cellular process ...
