What are some parts of a cell?
DNA is a molecule that contains instructions for how to build and maintain an organism. Genes are sections of DNA that contain instructions for specific traits like hair and eye colour. Chromosomes are the structures that house the genes. Human cells have 23 pairs of chromosomes.
DNA, Genes, and Chromosomes
DNA: DNA stands for deoxyribonucleic acid, which is a chemical found in almost all living organisms. It stores genetic information that can be passed from one generation to the next. Genes: Genes are the basic physical and functional units of heredity. They are made up of DNA and act as instructions to make molecules called proteins. Chromosomes: Chromosomes are structures inside of cells that contain genetic information. Most living organisms have two sets of chromosomes; one set from each parent.
DNA is a chemical found inside most living things, including plants, animals, and even bacteria. Genes are sections of DNA that act as instructions for the body. Each gene contains a unique set of instructions to tell the body how to grow and develop. Chromosomes are structures made of DNA and proteins. Humans have 23 pairs of chromosomes, or 46 in total.
