Emily's symptoms include frequent headaches, light sensitivity, nausea and vomiting. The risk factors are her smoking habit and the birth control pills that she is currently taking. A possible diagnosis could be an acute condition which is caused by a serious interaction between her smoking activity and her birth control pills. It has been proven that women who smoke while on contraceptive therapy have an increased risk of heart attack and stroke. This is because nicotine increases heart rate and blood pressure, while certain hormones present in some birth control pills (such as estrogen) increase the tension on blood vessels. For further diagnosis, the healthcare professional should check Emily's blood pressure and ask her family history on blood clots, heart problems, or stroke cases.
Answer:
In E. coli promoter there are two consensus sequence which is located upstream to from the start site of the transcription. One consensus sequence is present at -10 and one at -35.
These consensus sequences are necessary to be recognized to start the transcription. It is recognized by the sigma factor which is a part of RNA polymerase. After recognition transcription starts.
The termination of transcription occurs by a rho protein. Rho is ATP dependent RNA stimulated helicase which disrupts the complex of RNA-DNA and terminates transcription.
