Next to the gene is the promoter. You may know the promoter already as the region where RNA polymerase binds to initiate transcription. Not all promoters have the same DNA sequence, even though RNA polymerase binds at all promoters.
February 16, 2016. Plaster of Paris is a wonderful art medium that is easy to use for creating things from moulds and free form artwork. It's a powdered substance that becomes a pourable mixture when combined with water. The mixture is light and thin enough that it fills in even the finest details on the mould.
Add 2 ounces of water to 1/3 of a cup of Plaster of Paris in your cup and stir until it is smooth. Set aside to begin hardening. 3. Rub a coat of petroleum jelly over the object being used as a mold. 4. Gently press the object into the partially hardened plaster of Paris so that it is not more than half way covered. 5. Label your cup with your name and period and place it at your lab station.
