Two copies of chromosome 11, one copy inherited from each parent, form one of the pairs. Chromosome 11 spans about 135 million DNA building blocks (base pairs) and represents between 4 and 4.5 percent of the total DNA in cells. Identifying the genes on each chromosome is an active area of genetic research.
For example, the hemoglobin beta gene (HBB) is found on chromosome 11p15.4. This means that the HBB gene lies on the short arm (p) of chromosome 11 and is found at the band labeled 15.4. With the advent of new techniques in DNA analysis, we are able to look at the chromosome in much greater detail.
Ultimately, one wishes to determine how genes—and the proteins they encode—function in the intact organism. Although it may sound counterintuitive, one of the most direct ways to find out what a gene does is to see what happens to the organism when that gene is missing.
At about 21.5 genes per megabase, chromosome 11 is one of the most gene-rich, and disease-rich, chromosomes in the human genome. More than 40% of the 856 olfactory receptor genes in the human genome are located in 28 single-gene and multi-gene clusters along the chromosome.
