Eukaryote Transcription vs. Prokaryote Transcription

Different Types of Transcription?


Eukaryotes and Prokaryotes are different in so many ways but also the same. I explained a lot of the same and different ways in the "Eukaryotic and Prokaryotic Cells" post. One thing I did not describe was the transcription process of each. 

When you begin discussing the process it can become a little grey when you are trying to define an eukaryote from a prokaryote simply because the processes of both are so similar. They do the exact same job but it must be done in different areas and one is a bit more complicated than the other. 

Eukaryotes have membrane bound organelles. Because of this, eukaryotes have a mitochondria and a nucleus where the DNA is held. This is extremely important since RNA is created using DNA. Prokaryotes on the other hand have transcription happen right out in the cytoplasm since there are not any membrane bound organelles and instead everything is floating within the cytoplasm. 

Because of fact that one type of cell has organelles and one does not the one with organelles must also move RNA after transcription out of either the mitochondria or nucleus and into the cytoplasm in order for translation to occur, while a prokaryote does not need to move the RNA anywhere for translation because it is already in the correct place.
