Human Chromosome 4 is one of the 23 pairs of chromosomes in humans. It contains about 190 million base pairs, making up approximately 6% of the total DNA in human cells. This chromosome is crucial for various biological functions and is involved in the regulation of several genes. Chromosome 4 is associated with several genetic disorders, including Huntington's disease and achondroplasia. It also plays a role in the development of certain traits and conditions, such as Parkinson's disease. Understanding this chromosome helps researchers explore its impact on health and disease.
