promotera cis- acting (see CIS -ACTIVE) NUCLEOTIDE sequence on a DNA molecule which promotes the initiation of TRANSCRIPTION by allowing the assembly of proteins, including RNA POLYMERASE (or its equivalent), in transcriptional complexes. see OPERON MODEL. The promoter generally lies UPSTREAM of the transcription start site.

Patient discussion about promoter
Q. I am interested in social service. So what can I do to promote a healthy pregnancy?
A. Hi friend, once you're pregnant, a regular checkup is the key. Your health professional might want to monitor your baby's growth and watch for problems that can only be detected by checking your blood pressure, urine, and blood regularly. Anything you do that harms your body harms your fetus. Take special care: To avoid: tobacco smoking, alcohol, drugs, chemicals, radiation (as from X-rays), and sources of infection. Keep your body temperature from getting too high [over 100.4° (38°)] by treating any fevers with acetaminophen (such as Tylenol) and avoiding exercise or activity that overheats you. Also avoid high-temperature hot tubs and saunas. Take extra-good care of yourself while you're pregnant. Everything healthy you do for your body benefits your growing fetus. Rest when you need it, eat well, and exercise regularly.More discussions about promoter
