For example, many types of RNA have been found to be catalytic ... their abundance, and their diversity of functions has led to the hypothesis that an "RNA world" may have preceded the evolution ...

RNA, or ribonucleic acid, is a essential biological molecule that plays a crucial role in various cellular processes. It is a polymeric molecule composed of nucleotides, each containing a ribose sugar ...

Specialized silencing systems evolved in eukaryotic lineages through proliferation and specialization of small-RNA biogenesis and effector factors. Genomes spawn new types of RNA silencing ...

In addition cyclophilins play roles in inflammation and cancer and are already the target of several clinical drugs such as cyclosporin A. Surprisingly, this family has been robustly identified as ...

The main types of rRNA include: Small Subunit rRNA ... The rRNA molecules fold into complex secondary and tertiary structures, forming domains and motifs that are essential for ribosome function. The ...

Their study, published in Nucleic Acids ... A distinction is made between different types of RNA with different functions. For example, tRNA (transfer RNA) is an adapter molecule that deciphers ...
