  • Title: Cloning and characterization of a transcription termination signal in bacteriophage lambda unresponsive to the N gene product.
    Author: Honigman A.
    Journal: Gene; 1981 Apr; 13(3):299-309. PubMed ID: 6455329.
    Abstract:
    The pHA10 plasmid was designed for the cloning and selection of transcriptional termination signals. This study demonstrates the use of pHA10 as a cloning vehicle in the selection and characterization of an N-unresponsive terminator. Following the random cloning of lambda DNA, and N-unresponsive transcription terminator was isolated. Hybridization of in vivo 32P-labeled RNA to various DNA fragments, using the Southern (1975) blotting technique, revealed that the transcriptional barrier that cannot be overridden in the presence of N is located close to the end of gene J of lambda DNA. The terminator determines the 3'-end of the pL operon and prevents the transcription of the anti-sense DNA strand of lambda late genes. The primary structure and other characteristics of this terminator are now under investigation.
