Claude finds a CRISPR-like repeating segment in the DNA of giant phages; its function is unknown

In a day, SI noticed something in viral DNA that looks like a gene editor, but what it actually is remains for people to find out.
According to Scientific American, the segment was found next to a reverse transcriptase gene in the DNA of "jumbo" bacteriophages (viruses with unusually large genomes); the repeats lie in noncoding RNA regions. The researchers believe such a pattern has so far been found only in these viruses — not in other viruses, bacteria or humans. Eric Kauderer-Abrams, Anthropic's head of life sciences, says the function of the domain and the repeats is unknown and that it is "too early to speculate" about applications; the result was released early to engage the community. The analysis, the researchers say, took about a day instead of weeks or months. Verification by independent groups is limited so far.
