text: The mRNA is then exported from the nucleus to the cytoplasm , where it is bound to ribosomes and translated into its corresponding protein form with the help of tRNA . In prokaryotic cells , which do not have nucleus and cytoplasm compartments , mRNA can bind to ribosomes while it is being transcribed from DNA .
simplified: Then the mRNA moves from the nucleus to the ribosomes in the cytoplasm to form proteins .
