Chromosome 5 is one of the 23 pairs of chromosomes found in humans. It contains about 181 million base pairs and is responsible for carrying approximately 1,500 genes. These genes play crucial roles in various biological functions, including growth, development, and the regulation of certain diseases. Abnormalities in chromosome 5 can lead to genetic disorders. For example, Cri du Chat syndrome is caused by a deletion of a portion of this chromosome, leading to developmental issues and distinctive physical features. Understanding chromosome 5 is essential for studying genetics and its impact on human health.
