The above image represents the structure of a chromosome. Chromosomes are thread-like structures present inside the nucleus of animal and plant cells. Each chromosome is made of protein and a single molecule of deoxyribonucleic acid (DNA).

The above structure represents base pairing patterns in DNA. The basic building blocks of DNA are nucleotides, which are composed of a sugar group, a phosphate group, and a nitrogen base. The sugar and phosphate groups link the nucleotides together to form each strand of DNA. Adenine (A), Thymine (T), Guanine (G) and Cytosine (C) are four types of nitrogen bases. These 4 Nitrogenous bases pair together in the following way: A with T and C with G.
