Quote:
Project: CRISPR
* The CRISPR elements are part of a prokaryotic defence system directed against external attacks by e.g. viruses and may be viewed as a simple immune system of microorganisms.
By employing RNA World to systematically screen organisms for the presence of the various types of this defence machinery, we hope to acquire important information on the global distribution and varieties of this system. There is an enormous repertoire of potential applications to the results of such analyses ranging from the improvement of industrially relevant microbial food production to novel ways of coping with multi-drug resistant pathogenic bacteria.
How is this supposed to explain why the WUs have to be so short???? Can you explain this in humanly understandable English?
