Meghna Thapar 5 years, 7 months ago

Genes are the functional units of chromosomes which transmit the heredity information from parents to offsprings. These are located on chromosomes.

The nucleus contains chromosomes, which are visible as rod-shaped structures only when the cell is about to divide. Chromosomes contain information for inheritance of features from parents to next generation in the form of DNA (Deoxyribo Nucleic Acid) molecules. Chromosomes are composed of DNA and protein. DNA molecules contain the information necessary for constructing and organising cells. Functional segments of DNA are called genes.
