Loading of Amino Acids onto RNA in a Putative RNA‐Peptide World [PDF]
, 2023 RNA is a molecule that can both store genetic information and perform catalytic reactions. This observed dualism places RNA into the limelight of concepts about the origin of life.

Novel endoribonucleases as central players in various pathways of eukaryotic RNA metabolism [PDF]
, 2010 For a long time it has been assumed that the decay of RNA in eukaryotes is mainly carried out by exoribonucleases, which is in contrast to bacteria, where endoribonucleases are well documented to initiate RNA degradation.

Axon micro-dissection and transcriptome profiling reveals the in vivo RNA content of fully differentiated myelinated motor axons [PDF]
, 2020 Axonal protein synthesis has been shown to play a role in developmental and regenerative growth, as well as in the maintenance of the axoplasm in steady state.

Cold Spring Harbor Perspectives in Biology, 2018 Although we live in the remnants of an RNA world, the world of drug discovery and chemical probes is firmly protein-centric. Developing highly selective small molecules targeting RNA is often considered to be an insurmountable challenge. Our goal is to demystify the design of such compounds.

Lipid-Assisted Polymerization of Nucleotides
Life, 2019 In addition to being one of the proponents of the “Lipid World hypothesis”, David Deamer, together with other colleagues, pioneered studies involving formation of RNA-like oligomers from their ‘non-activated’, prebiotically ...

Life, 2023 How functional peptides may have arisen is a significant problem for the scenario of the RNA world. An attractive idea, the direct RNA template (DRT) hypothesis, proposes that RNA molecules can bind amino acids specifically and promote the synthesis of ...

RNA-specific ribonucleotidyl transferases [PDF]
, 2007 RNA-specific nucleotidyl transferases (rNTrs) are a diverse family of template-independent polymerases that add ribonucleotides to the 3'-ends of RNA molecules.

An Aminoisoxazole‐Based Proto‐RNA [PDF]
, 2023 The RNA world hypothesis predicts that life started with the development of replicating and catalytically active RNA, which evolved in a process of molecular evolution to increasingly complex chemical structures.

Maf1-mediated repression of RNA polymerase III transcription inhibits tRNA degradation via RTD pathway [PDF]
, 2012 tRNA precursors, which are transcribed by RNA polymerase III, undergo end-maturation, splicing and base modifications. Hypomodified tRNAs, such as tRNAVal(AAC), lacking 7-methylguanosine and 5-methylcytidine modifications, are subject to degradation by a

Genetics and Molecular Biology, 2014 One of the major developments that resulted from the human genome sequencing projects was a better understanding of the role of non-coding RNAs (ncRNAs). NcRNAs are divided into several different categories according to size and function; however, one shared feature is that they are not translated into proteins. In this review, we will discuss relevant
