Both genes and chromosomes are made from DNA. Genes are the basic functional unit of heredity and comprise a small stretch of DNA. Chromosomes are DNA and associated proteins, which form a complex organisation and are present as chromatin fibres in the nucleus. At the time of cell division, chromatin fibres further coil and condense and appear as chromosomes.
