☆ Nitrogenous Bases Found in DNA :
☯ The four types of nitrogenous bases are found in DNA. These are adenine (A), guanine (G), thymine (T) and cytosine (C).
Always, adenine pairs with thymine and guanine pairs with cytosine (i.e., A = T and G ≡ C).
Due to this pairing, the two strands are complementary to each other. The sugar - phosphate chains form the sides of a ladder and nitrogenous bases gives a spiral ladder - like shape to the DNA molecule, called double helix and forms double helical structure of DNA.
