Chromosome 1 is the designation for the largest human chromosome. Humans have two copies of chromosome 1, as they do with all of the autosomes, which are the non-sex chromosomes. Chromosome 1 spans about 249 million nucleotide base pairs, which are the basic units of information for DNA.[4] It represents about 8% of the total DNA in human cells.[5]
It was the last completed chromosome, sequenced two decades after the beginning of the Human Genome Project.
