Congrats to the team. I&amp;#x27;m curious how this study, published in Nature, is different than this study:&lt;p&gt;&lt;a href=&quot;https:&amp;#x2F;&amp;#x2F;www.nature.com&amp;#x2F;articles&amp;#x2F;s41564-019-0612-5&quot; rel=&quot;nofollow&quot;&gt;https:&amp;#x2F;&amp;#x2F;www.nature.com&amp;#x2F;articles&amp;#x2F;s41564-019-0612-5&lt;/a&gt;&lt;p&gt;Published in Nature Microbiology. Maybe just the institution?</text><parent_chain></parent_chain></comment><story><title>Crispr-Resistant Viruses Build ‘Safe Rooms’ to Shield Genomes from Enzymes</title><url>https://www.ucsf.edu/news/2019/12/416116/crispr-resistant-viruses-build-safe-rooms-shield-genomes-dna-dicing-enzymes</url></story>

There are already theories that DNA was first invented by viruses to protect against cleaving by RNAases, and the presence of UDNA viruses suggests it. It would also explain how DNA had immediate selective advantage over RNA.</text><parent_chain></parent_chain></comment><story><title>Crispr-Resistant Viruses Build ‘Safe Rooms’ to Shield Genomes from Enzymes</title><url>https://www.ucsf.edu/news/2019/12/416116/crispr-resistant-viruses-build-safe-rooms-shield-genomes-dna-dicing-enzymes</url></story>
