Answer:
chemicals that cross the synaptic gap and bind to receptors on another neuron
found only in the central nervous system (the brain and spinal cord)
Explanation:
Neurotransmitters are defined as the chemicals that is transported from a nerve cell across the synaptic gap to the receptor of another neuron or a target cell such as a gland cell or a muscle cell.
Neurotransmitters are generated in the central nervous system (the brain and spinal cord) and are stored in synaptic vesicles.
"Hence, the correct answer is:
chemicals that cross the synaptic gap and bind to receptors on another neuron
found only in the central nervous system (the brain and spinal cord)".
DNA replication begins when something called Helicase (an enzyme) unwinds the helix structure of the DNA. It does this so that Primase can then come along and set down an RNA primer.
