Answer:
B) For a gene under negative repressible control, a small molecule is required to prevent the gene's repressor from binding to DNA.
Explanation:
Operon is usually present in prokaryotes. It has a group of genes being transcribed under the same promoter. So the genes are expressed together when required. An operon can be under negative or positive control. It can further be inducible or repressible.
Under negative repressible control the operon is normally in working condition. Repressor protein is present but unable to bind to the operator. When a corepressor binds to repressor, it is activated and finally binds to the operator halting the transcription process. Hence the small molecule (corepressor) leads to binding of repressor to DNA and not the other way round. A small molecule is required to prevent the gene's repressor from binding to DNA in case of negative inducible operon.
Inhaled oxygen enters the lungs and reaches the alveoli. ... Oxygen passes quickly through this air-blood barrier into the blood in the capillaries. Similarly, carbon dioxide passes from the blood into the alveoli and is then exhaled.
Since the person is diagnosed and has been confirmed of having anti-social personality disorder, it means the patient does not have any thought of what is right and wrong and that the individual will likely ignore the feelings of others by that the nurse should still understand what the patient is going through and politely answer in a way that won't affect the client and in the same time, the nurse shouldn't be affected with what the client told him or her.
