Abstract
Precursor mRNA (pre-mRNA) molecules, sedimenting at greater than 45 S, from erythroid-enriched bone marrow cells of the rabbit and hemoglobin mRNA molecules from rabbit reticulocytes were investigated by electron microscopy. Four of 98 measured pre-mRNA molecules had a length between 15 and 17.1 mum. In some of the pre-mRNA molecules a characteristic condensed structure was observed at one end, strikingly resembling the structure of the mRNA molecules.
