Answer: Nervous System
Explanation:
Due to nerve cells dying.
Answer:
A) A corepressor must be present
Explanation:
The key to operon expression lies in the sequence of the operator and the presence or absence of a repressor. When the repressor binds the operator, it prevents RNA polymerase from initiating transcription. The capability of the repressor to bind the operator and inhibit transcription depends on the conformation of the repressor, which is regulated allosterically by a key compound in the metabolic pathway, such as lactose or tryptophan. In a repressible operon, such as the tryptophan (or trp) operon, the repressor is unable to bind to the operator DNA by itself. Instead, the repressor is active as a DNA-binding protein only when complexed with a specific factor, such as tryptophan , which functions as a corepressor.
When tryptophan is plentiful, tryptophan molecules act as corepressors by binding to the (1) inactive repressor and (2) change its shape, allowing it to bind to the operator, (3) preventing transcription of the structural genes
Answer:
they have a high chance of being related
Explanation:
Out of the following given choices;
<span>A. </span>The sodium channels would open and close randomly, regardless of the presence of light.
<span>B. </span>The sodium channels would remain closed in the light and the dark, even when cGMP decreases after light stimulation.
<span>C. </span>The sodium channels would remain open in the dark and close rapidly to the light.
<span>D. </span>The sodium channels would remain open longer, even when cGMP decreases after light stimulation.
The answer is D. cGMP maintain the sodium channels open when there is no light stimulation. This ensures that there is high intracellular Ca2+ concentration due to the Na+/Ca2+-K+ exchanger. When cGMP is hydrolyzed in light stimulation cascade, the channels close causing hyperpolarization of the rod cells.
