Choose all true statements about the difference between translation at free ribosomes versus bound ribosomes. - Free ribosomes are made in cytoplasm, whereas bound ribosomes are made in the nucleus. - Free ribosomes produce proteins in the cytosol, whereas bound ribosomes produce proteins inside the nucleus. - Bound ribosomes produce proteins that are exported from the cell, whereas free ribosomes make proteins for the nucleus.
