To begin with attempt to check whether there are any relatives I can contact, to illuminate them of the circumstance, and dangers of not transfusing, and talk about if these are genuinely the little girls wishes, and on the off chance that she comprehended that not accepting a transfusion could conceivably mean passing, and on the off chance that she was of sound personality when she settled on this choice. in the event that so then I would regard the desires and religious convictions of the patient and not transfuse, paying little respect to how troublesome, or my own perspectives.
Answer:
Hemoglobin is responsible for binding and transporting oxygen in the body. It is a tetrameric protein that is found in high concentration in red blood cells (erythrocytes, red blood cells). Each hemoglobin molecule is made up of four subunits: two of the alpha type and two of the beta type, and each subunit can bind an oxygen molecule through its heme group.
Structure studies have shown that hemoglobin can adopt two conformations, called T (tense) and R (relaxed). Deoxyhemoglobin (in blue) is in state T, and the union of oxygen (in red) causes the transition to state R. The animation shows a close view of the heme group (in white, balls and rods) of one of the subunits of hemoglobin. In the deoxygenated state (T), the iron atom is not coplanar with the rest of the heme group due to its association with the histidine side chain. The union of oxygen displaces the iron atom so that it remains coplanar with the rest of the heme group, which in turn drags histidine, producing a larger-scale conformational change that affects the entire protein.
Hemoglobin can be considered as a tetramer formed by two alpha-beta dimers. The conformational change associated with the transition from T to R mainly affects the relative position of these two dimers (rather than the interactions between the alpha and beta subunits within a dimer). This is illustrated in the last stretch of the animation (drawn in black and white).
Answer:
A. The gene for surface protein was transcribed and translated.
Explanation:
Because all living organisms use the same genetic code, it is possible to express genes from one organism in the other. In this case, the DNA sequence that corresponds to the hepatitis B surface protein gene has been inserted into the banana, and the protein is expressed.
For the protein to be expressed, the gene must have been successfully transcribed into an mRNA by the banana plant machinery. This mRNA has then been translated into a protein that means the hepatitis B surface protein is now present in the cell.
