title: Electron microscopic mapping and sequence analysis of the terminator for the early message of E. coli phage T7.
abstract: The terminator position of T7 early messenger RNA was determined by electron microscopic measurements. The end of the RNA was mapped at a position 18.9% from the left end of T7 DNA, and 145 +/- 25 nucleotides from the right end of the Hpa I fragment Q. The sequence of the Hpa I Q fragment was determined around this position, and a terminator-like structure was detected in position 193 to 169 from the right end of fragment Q.
