Chromosome 3 is one of the 23 pairs of chromosomes found in humans. It is the third largest chromosome, containing about 196 million base pairs, which make up approximately 6.5% of the total DNA in human cells. This chromosome plays a crucial role in various biological functions and contains many genes that are important for growth, development, and overall health. Several genetic disorders are associated with Chromosome 3, including Bardet-Biedl syndrome and Wilms tumor. Researchers study this chromosome to understand its role in diseases and to develop potential treatments. The genes located on Chromosome 3 are involved in processes such as cell division and immune response.
