WebIn the case of the lac operon, there is a low level of expression even when it is shut-off by the lac repressor. This means a small amount of the ß-galactoside permease (encoded by lacY) is always present. … WebActivators and Repressors. There are two different types of gene regulation: positive and negative. Activators (and sometimes inducers) instigate positive regulation, and repressors instigate negative regulation. When an activator or inducer binds to an operon, the transcription process either increases in rate or is allowed to continue. chinesisches horoskop 2012
