Verified step by step guidance1
Understand that DNA is a type of nucleic acid, which is a macromolecule essential for all known forms of life.
Recognize that the basic building blocks of DNA are nucleotides.
Each nucleotide in DNA is composed of three components: a sugar molecule (deoxyribose), a phosphate group, and a nitrogenous base.
The nitrogenous bases in DNA are adenine (A), thymine (T), cytosine (C), and guanine (G).
DNA forms a double helix structure, where two strands of nucleotides are linked by hydrogen bonds between complementary bases (A with T and C with G).
