chromosome A chromosome is a long DNA molecule with part or all of the genetic material of an organism. In most chromosomes the very long thin DNA fibers are coated with packaging proteins; in eukaryotic cells the most important of these proteins are ...

s. People normally have two copies of this chromosome. Chromosome 4 spans more than 186 million base pairs (the building material of DNA) and represents between 6 and 6.5 percent of the total DNA in cells.

Genomics

The chromosome is ~191 megabases in length. In a 2012 paper, 775 protein-encoding genes were identified on this chromosome.Chen LC, Liu MY, Hsiao YC, Choong WK, Wu HY, Hsu WL, Liao PC, Sung TY, Tsai SF, Yu JS, Chen YJ (2012) Decoding the disease-associated proteins encoded in the human chromosome 4. J Proteome Res 211 (27.9%) of these coding sequences did not have any experimental evidence at the protein level, in 2012. 271 appear to be membrane proteins. 54 have been classified as cancer-associated proteins.

). Among various projects, the collaborative consensus coding sequence project ( CCDS) takes an extremely conservative strategy. So CCDS's gene number prediction represents a lower bound on the total number of human protein-coding genes.
