What three molecules make up DNA
nan
DNA (Deoxyribonucleic Acid) is a long, complex molecule that carries genetic information. The three major components that make up DNA are:
1. Deoxyribose: This is a sugar molecule that forms the backbone of DNA. It is a type of sugar that contains five carbon atoms and is structurally similar to ribose, which is a component of RNA (Ribonucleic Acid).
2. Phosphate: The phosphate molecule is a negatively charged ion that links each sugar molecule to the next one in the DNA strand. This creates a long chain of repeating sugar-phosphate units, forming the backbone of the DNA molecule.
3. Nitrogenous Bases: These are the chemical compounds that contain nitrogen and form the “rungs” of the DNA ladder. There are four types of nitrogenous bases found in DNA: Adenine (A), Thymine (T), Cytosine (C), and Guanine (G). The sequence of these bases determines the genetic code that is carried by DNA.
Together, Deoxyribose, Phosphate, and Nitrogenous Bases make up a DNA molecule.
