What to know about Institutional Prestige (HKUST)

Researchers at the Hong Kong University of Science and Technology have developed a DNA-guided CRISPR-Cas system called SLEUTH that can target and cleave RNA. The system aims to provide a more stable, cost-effective, and precise alternative to traditional RNA-guided CRISPR and RNA-interference tools for diagnostics and therapeutics.

Claim 1: “Synthetic DNA has significantly greater chemical stability than RNA and does not require specialized cold-chain storage.”
VERIFIED BY REFERENCE
General scientific knowledge from Wikipedia regarding the chemical structure of DNA vs RNA confirms that DNA is more stable. While 'cold-chain' is a logistical application, the chemical stability is a verified fact.
