Sequence organization of the beta-globin mRNA precursor.
The sequence organization of the beta-globin mRNA precursor has been determined directly by analyzing the resistant fragments from the RNase A digestion of the precursor RNA-globin cDNA hybrid. Three fragments are obtained which proves that the beta-globin mRNA sequence in its precursor is split into three discontinuous segments. The two intervening sequences in the beta-globin gene are therefore transcribed and removed during mRNA maturation.
