By Regina Bailey. Nucleic acids allow organisms to transfer genetic information from one generation to the next. There are two types of nucleic acids: deoxyribonucleic acid, better known as DNA and ribonucleic acid, better known as RNA.When a cell divides, its DNA is copied and passed from one cell generation to the next generation. DNA is organized into chromosomes and found within the nucleus of our cells.y Regina Bailey. Nucleic acids allow organisms to transfer genetic information from one generation to the next.

A typical neuron consists of a cell body (soma), dendrites, and an axon. The term neurite is used to describe either a dendrite or an axon, particularly in its undifferentiated stage.
About Neurons. The basic working unit of the nervous system is a cell called a neuron. The human brain contains about 100 billion neurons. A neuron consists of a cell body containing the nucleus, and special extensions called axons (pronounced AK-sonz) and dendrites (pronounced DEN-drahytz).Neurons communicate with each other using axons and dendrites.ensory Neurons. Sensory neurons carry information from the sense organs (such as the eyes and ears) to the brain. Synapses. The space between the end of a nerve cell and another cell.
