Answer: Ribose nucleotides and the nitrogenous bases
Explanation: RNA consists of ribose nucleotides (nitrogenous bases appended to a ribose sugar) attached by phosphodiester bonds, forming strands of varying lengths. The nitrogenous bases in RNA are adenine, guanine, cytosine, and uracil, which replaces thymine in DNA.
The electrochemical impulse is composed of an action potential travelling from the dendrite to the cell body to the axon of the neuron. The main neurotransmitter is acetylcholine which is released at either the synapse or the neuromuscular junction.
