One set is inherited from the father, and one set is inherited from the mother. A DNA is a sort of a bio molecule. The entire DNA in cells can be found in individual pieces that are called chromosomes. The main difference between DNA and chromosome is regarding the role of genes. DNA stands for deoxyribonucleic acid. The DNA is basically made up of cytosine, adenine, thymine and guanine. When you arrange these four bases to create a particular segment, it is called a gene.
Chromosomes and genes. A gene is a section of DNA [DNA: The material inside the nucleus of cells, carrying genetic information. DNA stands for Deoxyribonucleic Acid. ] that carries the code for a particular protein.Different genes control the development of different characteristics of an organism. Many genes are needed to carry all the genetic information for a whole organism. Chromosomes, found in the cell nucleus, contain many genes.Nucleus, chromosome and gene. The number of genes and chromosomes varies from species to species. gene is a section of DNA [DNA: The material inside the nucleus of cells, carrying genetic information.
