Anthropic reports new enzyme system with CRISPR-like repeats
The system’s function remains unknown and the research has not yet been peer-reviewed.
Anthropic says Claude helped find a previously undescribed enzyme system in bacteriophages. The system shares some similarities with CRISPR, but its biological function remains unknown.
Anthropic has announced a new research programme for biology. According to the company, Claude helped find a system in the DNA of bacteriophages, viruses that infect bacteria. The system consists of a reverse transcriptase, an accompanying gene and a series of repeating DNA sequences.
The researchers call the system array-associated reverse transcriptases, abbreviated to ART. According to Anthropic, the repeats bring to mind a CRISPR array, in which short DNA or RNA sequences can form part of a biological defence system. That similarity does not mean that ART has the same function as CRISPR.
Claude is said to have searched large quantities of DNA sequences and identified an unusual pattern. Human researchers then assessed the candidate and conducted laboratory experiments. Anthropic says the repeats are transcribed into short RNA molecules.
The function of ART is not yet known. Anthropic reports that the system combines characteristics also found in several other biological systems, but that says nothing yet about its usefulness for gene therapy or gene editing. Additional experiments are needed for that.
The announcement appears in a company blog and is linked to a preprint. The study has therefore not yet been independently peer-reviewed. Anthropic also presented the initial results itself, making independent confirmation important.
For now, the significance of the result lies mainly in the research method: an AI system can help find patterns in large genetic databases and select candidates for laboratory research. Whether ART truly reveals a new biological function and later proves practically useful remains unknown.
Fact-check Approved · Nour Haddad — AI agent
This check was carried out by AI: every claim was re-tested against the sources. Even an approved article can contain errors — stay critical.
The text remains close to the results reported by Anthropic and explicitly notes their status as a preprint. Independent confirmation of the biological function or practical applicability is still lacking.

Editor's note
The results come from Anthropic and a preprint that has not yet been peer-reviewed. The discovery of ART and the initial laboratory observations are therefore described as company claims; the function and possible applications are unknown.Sources
