A short stretch of RNA with a free 3' end, bound by complementary base pairing to the template strand, that is elongated with DNA nucleotides during DNA replication.
Two general types of cells are found in the nervous system: neurons and neuroglia. A. Neurons 1. Consist of three main partsâdendrites (conduct impulses to cell body of neuron); cell body of neuron; and axon (conducts impulses away from cell body of neuron) 2.he nervous system transmits information rapidly by means of nerve impulses conducted from one body area to another. The nervous system is made up of the brain and spinal cord, and the many nerves of the body.
Neurons. Neurons, or nerve cells, carry out the functions of the nervous system by conducting nerve impulses. They are highly specialized and amitotic. This means that if a neuron is destroyed, it cannot be replaced because neurons do not go through mitosis.he actual nerve cell is the neuron. It is the conducting cell that transmits impulses and the structural unit of the nervous system. The other type of cell is neuroglia, or glial, cell. The word neuroglia means nerve glue..
