WebIn eukaryotic cells, the transcription process takes place within the nucleus and the resulting mRNA transcript is transported to the cytoplasm where it's involved in translation. In prokaryotes, on the other hand, transcription takes place in the cytoplasm where the genetic material is located. WebThe operation of making a ribonucleic acid (RNA) copy of a DNA (deoxyribonucleic acid) mol, called transcription, are necessary for all forms of life. The mechanisms involved in transcription are similar among organisms but can differ in view, especially between prokaryotes and eukaryotes. There are several types of RNA molecules, and all are …
