WebHere, we show that fibrillarin (FBL), a critical methyltransferase for ribosomal RNA (rRNA) processing in nucleoli, is one of the proteins highly expressed in pluripotent embryonic stem (ES) cells. Stable expression of FBL in ES cells prolonged the pluripotent state of mouse ES cells cultured in the absence of leukemia inhibitory factor (LIF). WebThere are two main processes that must occur to synthesize proteins: transcription and translation. During the process of transcription —which occurs in the nucleus—an mRNA molecule is created by reading the DNA. Note that DNA never “becomes” RNA; rather, the DNA is “read” to make an RNA molecule. brydge tastatur https://qift.net
