A gene is a genetic-coded segment of DNA, packaged together into structures called chromosomes. Chromosomes are found in the nucleus of each cell. Function. The genetic information is not used directly from the DNA. Ribonucleic acid (RNA) is used, and transcription is the process by which this code is copied from DNA into RNA (ribonucleic acid).
