Chromosome is a microscopic thread-like structure that is made up of proteins and they are found in nucleus of each cell of animals, humans and plants. Chromosomes are like small threads that are made up of DNA and proteins . DNA stands for deoxyribonucleic acid, which is the template on which all the structures of the body are created and maintained. There are several genes in each chromosome. Chromosomes is made up of proteins and DNA organized into genes. Studying the 23 pairs of chromosomes and their functions is an important part of biology to understand various developmental pathways and diseases associated with these genes. What Are Chromosomes Made Of? At its core, a chromosome is made up of DNA , short for deoxyribonucleic acid. This DNA is coiled around protein structures called histones, much like thread wound around a spool. The resulting structure is known as chromatin.
