Substrate Binding by RNA Polymerase RNA polymerase has t binding sites for ribonucleoside triphosphates: the initiation site and the elongation site. The initiation site has a greater Km for NTPs than the elongation site. Suggest what possible significance this fact might have for the control of transcription in cells.
The RNA polymerase from bacteriophage T7 diff ers structurally from prokaryotic and eukaryotic RNAPs and is extremely specifi c for its own promoter. Why do these properties make T7 RNAP useful in experiments with recombinant DNA?

TRUE FALSE EF-Ts factor regenerates EF-Tu/GDP from EF-Tu/GTP for the next round of elongation cycle in prokaryotic translation. The sigma o subunit of RNA polymerase is replaced by NusA to recognise the promoter region of a gene. The -10 and -35 sequences in E. coli DNA are referred to as untranslated region. In human, translation begins before transcription of an mRNA completes. The distal histidine stabilises the iron in heme group of a deoxyhaemoglobin. Receptor for epinephrine consists of seven transmembrane helices. Membrane receptors bind to hydrophobic signaling molecules. Amino acids, glucose and fatty acids are taken up by transporters into liver cells. Glycerol and fatty acids are synthesized from the intermediates of glycolysis. Synthesis of fatty acid occurs in cytoplasm. Triacylglycerol can be obtained from diet and also synthesized in liver cells. Ammonia and keto acid are formed in transamination.

Keeping in mind the three main processing events that occur in eukaryotes (5' capping, 3' cleavage and intron splicing) would it be reasonable to conclude that the mature RNA would contains exons, a promoter region (to the left of the transcription site) and a poly A tail?
