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.
Neuron: Nerve cell. The basic units of the central nervous system, neurons are responsible for the. transmission of nerve impulses. Unlike any other cell in the body, neurons consist of a central cell body as well. as several threadlike arms called axons and dendrites, which transmit nerve impulses.
