Abstract
The average size and base composition of the covalently integrated RNA segment in supercoiled ColE(1) DNA synthesized in Escherichia coli in the presence of chloramphenicol (CM-ColE(1) DNA) have been determined by two independent methods. The two approaches yielded similar results, indicating that the RNA segment in CM-ColE(1) DNA contains GMP at the 5' end and comprises on the average 25 to 26 ribonucleotides with a base composition of 10-11 G, 3 A, 5-6 C, and 6-7 U.Entities:
