Chromosome 1 is the largest human chromosome, made up of around 249 million nucleotide base pairs and representing approximately 8% of the entire DNA within a human cell. Research into chromosome 1 has shown that it contains around 4,220 genes and was the last gene to have its DNA sequencing completed by The Human Genome Project, nearly twenty years back.
