Answer:
D
Explanation:
An enzyme called poly (A) polymerase (PAP) is part of the same protein complex that cleaves the pre-mRNA and it immediately adds a string of A nucleotides, called the poly (A) tail, to the 3′ end of the just-cleaved pre-mRNA. The poly (A) tail added protects the mRNA from degradation, aids in the exportation of the mature mRNA to the cytoplasm and helps in binding proteins involved in initiating translation.

Whether the effect of a neurotransmitter is excitatory or inhibitory depends on the receptor it binds to.
<h3>What is Neurotransmitter?</h3>
A neurotransmitter may be defined as the chemical substances present within the synaptic vesicles and transmitting the impulse through synapses.
Examples of excitatory neurotransmitters are glutamate, norepinephrine, epinephrine, etc. Such neurotransmitters promote the electrical impulse and allow the passage of messages.
Examples of inhibitory neurotransmitters are serotonin, glycine, GABA, etc. Such neurotransmitters inhibit the passage of electrical impulses and block information.
Therefore, it is well described above.
