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.
3. axon. The dendrites receive impulses from sensory receptors or other neurons and send them towards the cell body, which contains the nucleus. Impulses are then conducted along the axons full length away from the cell body to connect with the dendrites of another neuron, muscle, organ or gland of some kind.. Conductivity: This means neurons are also able to transfer an impulse along the full length of their axons and then on to other neurons, muscles or glands. Like the electrical wiring in your house. Neurons are always excited by a stimulus first, before that stimulus is conducted to the next nerve, muscle or gland.
