CRISPR critters: Scientists identify key enzyme in microbial immune system
Date:9/9/2010

d prokaryotes. Understanding how these small RNA molecules work can improve our basic understanding of cell biology and provide important clues to the fundamental role of RNA in the evolution of life.

Says Doudna, "By investigating how bacteria produce and use small RNAs for selective gene targeting, we hope to gain insight into the fundamental features of the pathways that have proven evolutionarily useful for genetic control, both in the bacterial world and in the world of eukaryotes. Right now it looks like bacteria and eukaryotes have evolved entirely distinct pathways by which RNAs are used for gene regulation and that is pretty amazing!"
