Hi there!
In a prokaryotic cell, DNA is present in the cytoplasm in a specific region called nucleoid. While in a eukaryotic cell, DNA is present within the nucleus.
The mRNA is present in the nucelus and is transported to cytoplasm during translation. The tRNA is present in cytoplasm. Moreover, the rRNA is present in the nucleolus region and is also seen as a component of the ribosomes in a cell.
Thanks
