Need genetics professor or wiz!

Incorrect Question 4 of 12 Sapling Learning macmillan learning Which of the following statements describe how inducers cause changes in gene expression? inducers bind to activator proteins and enhance the ability of the activator to bind DNA inducers enhance transcription of all genes inducers are small molecules that bind to DNA to enhance transcription of target genes inducers are ions that are essential for the function of RNA polymerase inducers allow transcription of specific genes Incorrect. One or more selected answers are incorrect. Inducers affect the expression of genes by binding to proteins that are responsible for regulating gene expression. However, inducers do not bind to general transcription factors or the transcriptional machinery itself, and consequently inducers do not cause global changes in gene expression within a cell. Map

Explanation / Answer

Answer- Inducers are small molecules that bind to DNA to enhance transcription of target gene.

Discription-Inducers function by binding to activators. Activators generally bind poorly to activator DNA sequences unless an inducer is present. Activator binds to an inducer and the complex binds to the activation sequence and activates target gene. Removing the inducer stops transcription.small inducer molecule is required, the increased expression of the target gene is called induction.
