Answer:
Everything else is the same. Just like DNA, G and C are paired together. But on RNA, the A is different. It’s not paired with T, but with U.
RNA pairs:
A - U ( Adenine to Uracil )
G - C ( Guanine to Cytosine )
The nucleus contains the <u>DNA</u> (Deoxyribosenucleic Acid). It codes for all the hereditary characteristics an organism has and it is packaged into chromosomes within the nucleus.
<span>Myelination enhances the speed of action potential propagation.
The difference between myelinated and unmyelinated axons are in the propagation of action potential. In unmyelinated axons, the action potential travels continuously through the axons. On the other hand, among the myelinated nerve fibres, transmembrane currents can only occur at the nodes of Ranvier where the axonal membrane is exposed, so the excitation of the axonal membrane jumps from node to node. This propagation is called saltatory conduction and this movement of depolarization wave is much faster than in unmyelinated fibres.</span>
