WebIn cells, transcription is the process that resembles copying a recipe onto a 3x5 card and sliding it under the office door. The 3x5 card, with the recipe written on it, is analogous to a messenger RNA transcript (mRNA transcript, for short). An mRNA transcript is a single strand of RNA that encapsulate the information contained in a gene. WebRNA polymerase III is also located in the nucleus. This polymerase transcribes a variety of structural RNAs that includes the 5S pre-rRNA, transfer pre-RNAs (pre-tRNAs), and small nuclear pre-RNAs.The tRNAs …
