WebApr 9, 2024 · Evidence of localized mRNAs and protein synthesis in single-cell and multicellular organisms has revealed that mRNA localization has a range of functions … WebJan 3, 2024 · Note that catalysis of the synthesis of most of the RNA in a eukaryotic cell (rRNAs) is by RNA polymerase I. With the help of initiation proteins, each RNA polymerase initiates transcription at a promoter sequence. Once initiated, the RNA polymerases then catalyze the successive formation of phosphodiester bonds to elongate the transcript.
