WebEukaryotic mRNAs must undergo several processing steps before they can be transferred from the nucleus to the cytoplasm and translated into a protein. The additional steps involved in eukaryotic mRNA maturation … WebIn eukaryotic protein synthesis, it is usually the cytoplasmic ribosomes that translate nuclear genes. Several aspects of eukaryotic protein synthesis are more complex. The ribosomes of eukaryotic cells are larger and contain more rRNA and protein molecules than those of prokaryotes.
