RNA (ribonucleic acid) is a nucleic acid polymer where the carbohydrate is ribose. RNA is generally single-stranded, as DNA is transcribed by RNA polymerases into mRNA (messenger RNA), which is ...

Finally, we added evoPreQ1 RNA pseudoknot sequence on both RNA molecules to reduce RNA degradation from 3’-ends, resulting in crRNA-MS2 and BoxB-petracrRNA. We next sought to extend this approach to ...

The FSE of coronavirus has been characterized as a pseudoknot and associated with the −1 PRF slippage event at the 7-residue slippery site. (8−13) The SARS-CoV-2 FSE is an 84-nt segment and contains, ...

Pseudoknot; DB, Dumbbell; PN, 5′-CACAG-3′ pentanucleotide; eEF1A, Eukaryotic elongation factor 1A; YBX1, Y box-binding protein-1; PABP, Poly(A)-binding protein; PTB, Polypyrimidine tract-binding ...

Not only does Bennu contain evidence of ancient pools of liquid water — it also carries minerals crucial to life, amino acids, and the five nucleobases for DNA and RNA. As asteroids crash into ...

During infection, positive-stranded RNA causes a rearrangement of the host cell membrane, resulting in specialized membrane structure formation aiding viral genome replication. Double-membrane ...

Now Dimastrogiovanni et al. have used a technique called X-ray crystallography to visualize the interaction between Hfq and a small RNA molecule called RydC. These experiments reveal that a particular ...
