. region of the DNA is transcribed into RNA, the sequence of the resulting RNA transcript will be ____. A. 5’-TCGGCAC-3’ B. 5’-CUAAUGA-3’ C. 5’-TGTAATC-3’ D. 5’-UGUAAUC-3’ E. 5’-GAUUACA’3’ 41.. hormone ( 125 I-hormone) for five minutes. A second sample of membranes was prepared and treated similarly with the addition of 125 I- hormone but this sample also contained a 1000-fold excess....

. to be sure to include the (NADH + H + ) from pyruvate oxidation, the 3 (NADH + H + ) from the Krebs cycle along with the 1 FADH2 from Krebs. Each of the (NADH + H + ) will yield 2.5 ATP. 4 X. increase the rate of the electron transport chain. 33/35 DNA is double stranded, anti-parallel and must follow base pairing rules (A with T, C with G). 34/3 4) Allosteric effectors bind at sites. ei...
