Question 3 5 out of 5 points During the transcription of a given portion of a DNA molecule _____. This makes sense for the cell because it would be energetically wasteful to create the proteins to process lactose if glucose was plentiful or lactose was not available. Lung tissue -- trachea -- nostrils -- circulatory system.
After binding to the promoter the RNA polymerase initiates RNA synthesis at the start point on the template strand. The activator protein will be bound to the operator which will turn on the.
