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.
â¢ Receives signals from other cells and sends them toward the axon. â¢ Sum up, or integrate, the incoming signals. â¢. Axon. The transmitting or conductive region of the neuron. â¢. The axon generates an action potential, an outgoing signal also called a nerve impulse, and conducts it to the next cell.â¢ Label the parts of this neuron: â¢ Neurons receive and integrate signals at one location and transmit an action potential at another location.Page 6. In most neurons, the cell body, or soma, is located centrally. â¢ Multiple similar processes, called dendrites, extend from the soma, forming a structure resembling the branches of a tree. â¢ A thin single process, called the axon, also extends from the soma.
