Tissue-specific transcription of the globin gene in isolated chromatin

RNA was transcribed from chrmation from mouse fetal liver or brain, by use of DNA-dependent RNA polymerase of Escherichia coli. Globin messenger RNA sequences in the transcript were measured with complementary DNA copied from globin messenger RNA with RNA-dependent DNA polymerase. Globin messenger RNA sequences were found in RNA newly transcribed from chromatin from erythropoietic tissue but not in that transcribed from brain chromatin.
