WebHumans normally have 46 chromosomes in each cell, divided into 23 pairs. Two copies of chromosome 1, one copy inherited from each parent, form one of the pairs. Chromosome 1 is the largest human chromosome, spanning about 249 million DNA building blocks (base pairs) and representing approximately 8 percent of the total DNA in cells. WebSince humans are thought to have about 100,000 genes, a total of about 100 million nucleotide pairs of coding DNA must be present in the human genome. That this is only about 3 percent of the total size of the genome leads one to conclude that less than 5 percent of the human genome codes for proteins.
