New research suggests that manufacturing plants within cells are picky about the widgets they build.
Instead of making a variety of proteins, these nuclear bodies may choose to produce only special products.
Developmental biologists and geneticists Maria Bana of Stanford University School of Medicine and his colleagues have found that some of these specialization may affect the development of embryos.
Barna was at a joint meeting of the American Institute of Cell Biology and the European Organization for molecular biology.
Nuclear bodies composed of many proteins and rna read the genetic instructions for copying from DNA to messenger rna.
The nucleus then translates these instructions into other proteins that build cells and perform cell functions.
Typical mammalian cells may carry 10 million nuclear bodies.
