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.
A neuron is an individual cell in the PNS or CNS that can be excited and conduct impulses along its axon. A nerve is a bundle of multiple neuron fibers that each are carrying their own signals. They are protected by connective tissue. Eventually the neuron fibers diverge away from the nerve to reach their destination. A neuron is a nerve cell. A synapse is a gap between the sending and receiving neurons, where there are neurotransmitters responsible for transporting chemicals to the r â¦ eceiving neuron.
