These are the nucleotides adenine, thymine, cytosine, and guanine—often referred to as A, T, C, and G. The pattern of nucleotides along a strand of your DNA is what forms the code that makes up your genetic blueprint.

It is often called the "control center" because it controls all the activities of the cell including cell reproduction, and heredity. Chromosomes are microscopic, threadlike strands composed of the chemical DNA (short for deoxyribonucleic acid).

The molecule inside cells that contains the genetic information responsible for the development and function of an organism. DNA molecules allow this information to be passed from one generation to the next.

Deoxyribonucleic acid, more commonly known as DNA, is a complex molecule that contains all of the information necessary to build and maintain an organism. All living things have DNA within their cells. In fact, nearly every cell in a multicellular organism possesses the full set of DNA required for that organism.

The sole purpose of DNA replication is to generate identical DNA molecules, as they are the blueprint that makes life possible.

DNA is responsible for carrying and transmitting hereditary materials or genetic instructions from parents to offspring. In addition to ensuring that all living things pass on their genetic information, DNA is essential for the synthesis of proteins.

Deoxyribonucleic acid or DNA is the molecule of heredity. It contains the genetic blueprint for life. For organisms to grow and repair damaged cells, each cell must be capable of accurately copying itself.
