A lack of which of the following molecules would result in the cell's inability to "turn off" genes?

Question

Quizplus · Accepted Answer

Corepressors are molecules that bind to repressors and activate them, leading to the inhibition of transcription of genes. Without corepressors, the cell would not be able to turn off genes. The other choices are involved in the regulation of gene expression but not specifically in "turning off" genes. Operons are a group of genes regulated together, inducers bind to repressors to remove inhibition, promoters are sites where RNA polymerase binds to initiate transcription, and ubiquitin is involved in protein degradation.
