The pL promoter is controlled by the cl repressor protein of bacteriophage A. In practice, a temperature-sensitive mutant of the cl repressor, cl857, is generally used to regulate pL-directed transcription. Cells carrying the temperature-sensitive cl repressor are first grown at 30°C, and 42°C

#Part-A Aptitude & General Biotechnology
  1. at 30°C the cl repressor prevents transcription directed by the pL promoter
  2. at 42°C the thermosensitive cl repressor is inactivated and transcription can proceed.
  3. at 30° the thermosensitive cl repressor is inactivated and transcription can proceed.
  4. at 42°C the cl repressor prevents transcription directed by the pL promoter
