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.
Nerves form a network of pathways for conducting information throughout the body. Neuron: Any of the impulse-conducting cells that constitute the brain, spinal column, and nerves, consisting of a nucleated cell body with one or more dendrites and a single axon. Also called nerve cell.erves form a network of pathways for conducting information throughout the body.
