Summary Introduction

To review:

The significance of fully saturation of hemoglobin with oxygen at 100 mmHg partial pressure of oxygen (PO2) and return to heart in the venous blood at 40 mmHg PO2, reflecting 75% of saturation.

Introduction:

The partial pressure of the gas is defined as the part of the volume occupied by that particular gas in the mixture of the gases. In the atmosphere, the oxygen occupies 21% of the total gases present in the atmosphere. The PO2 at the sea level is nearly 159 mmHg. The hemoglobin is a protein that functions as the carrier of the oxygen in the body.

Molecular Biology Please help with question. thank you You are studying the expression of the lac operon. You have isolated mutants as described below. In the presence of glucose, explain/describe what would happen, for each mutant, to the expression of the lac operon when you add lactose AND what would happen when the bacteria has used up all of the lactose (if the mutant is able to use lactose).5. Mutations in the lac operator that strengthen the binding of the lac repressor 200 fold 6. Mutations in the promoter that prevent binding of RNA polymerase 7. Mutations in CRP/CAP protein that prevent binding of cAMP8. Mutations in sigma factor that prevent binding of sigma to core RNA polymerase
Molecular Biology Please help and there is an attached image. Thank you. A bacteria has a gene whose protein/enzyme product is involved with the synthesis of a lipid necessary for the synthesis of the cell membrane. Expression of this gene requires the binding of a protein (called ACT) to a control sequence (called INC) next to the promoter. A. Is the expression/regulation of this gene an example of induction or repression?Please explain:B. Is this expression/regulation an example of positive or negative control?C. When the lipid is supplied in the media, the expression of the enzyme is turned off.Describe one likely mechanism for how this “turn off” is accomplished.
Molecular Biology Please help. Thank you. Discuss/define the following:(a) poly A polymerase (b) trans-splicing (c) operon
