DNA is a molecule that contains the genetic instructions used in the development and functioning of all known living organisms. DNA is composed of four nucleotides: adenine, thymine, cytosine, and guanine. DNA sequencing is the process of determining the exact order of nucleotides in a DNA molecule.

DNA (Deoxyribonucleic acid) is a molecule that carries genetic information in living organisms. The DNA molecule is made up of two strands that are intertwined in the shape of a double helix. DNA is typically composed of four different types of nucleotides: adenine (A), thymine (T), guanine (G), and cytosine (C).

DNA stands for deoxyribonucleic acid and it is the genetic material found in almost all living organisms. DNA was first discovered in 1869 by a Swiss scientist named Friedrich Miescher. DNA is made up of four different nitrogenous bases: adenine (A), guanine (G), cytosine (C), and thymine (T).
