WebGenes and Chromosomes. Genes are segments of deoxyribonucleic acid (DNA) that contain the code for a specific protein that functions in one or more types of cells in the body. Chromosomes are structures within cells that contain a person's genes. Genes are contained in chromosomes, which are in the cell nucleus. WebThus, a single gene, or transcription unit, can code for multiple proteins or other gene products, depending on how the exons are spliced back together.
