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.
Parts of a Neuron â¢Cell body âthe largest part of a neuron that contains the nucleus and most of the cytoplasm â¢Dendrites âshort, branched extensions that carry impulses from the environment or from other neurons toward the cell body â¢Axon âlong fibers that carry impulses away from the cell body
