For the four different types of bases found in the DNA molecule, ACGT is the acronym used. It stands for 4 bases of human DNA – adenine (A), cytosine (C), guanine (G), and thymine (T).
A molecule of DNA is made up of two complementary strands, wound around each other. Each strand of DNA is held together by bonds between these bases. These bases are very specific when it comes to pairing, adenine pairs with thymine only and cytosine with guanine, always.
