WebRibosomal siRNAs silence pre-rRNAs via the nuclear RNAi pathway. rRNA biogenesis is a multistep process, including a series of pre-rRNA processing, folding, and modification steps. Endogenous metabolic stresses and environmental stimuli can cause RNA processing disorders, leading to the accumulation of erroneous RNAs. Web31 aug. 2024 · Proteins are made from a sequence of amino acids rather than nucleotides. Transcription and translation are the two processes that convert a sequence of nucleotides from DNA into a sequence of amino acids to build the desired protein.
