Attached is an example of a mRNA wheel.
The codon UAA codes a stop codon. The mRNA wheel is read by starting to choose from the four letters at the centre the one that is the first in the codon. Then, on that quarter of the circle, choose from the four letters, the second in the codon. Repeat again the process for the 1/16 part you chose previously choosing now the last letter in the codon. You are now able to identify what is coded by the mRNA codon.
Answer:
(b) Are Voltage-gated channels
Explanation:
Transmitter gates ion channels are also called ionotropic neurotransmitter receptors as one or more parts of the ion channel serve as a receptor for specific neurotransmitters.
Binding of the specific neurotransmitter to the receptor stimulates the opening of the ion channels and allows the transmembrane transport of specific ion.
The voltage-gated ion channels are the ones that open and close in response to changes in the voltage across the plasma membrane.
For example, voltage-gated Na+ channels are opened in response to depolarization of the membrane only.
Answer:
I think it would be geographic range. Hope this helps.
