. of RNA • Ribosomal RNA, rRNA, is RNA that becomes part of the ribosome, the big molecular machine responsible for synthesizing proteins • Transfer RNA, tRNA, is used to bring correct amino acids. Micro RNAs (mRNAs) are important in regulating gene expression • others Transcription involves the synthesis of rRNA from DNA using RNA polymerase • RNA polymerase must unpair and unwind DNA. used...
