Chromosome 9

Chromosome 9 is one of the 23 pairs of chromosomes in humans. Humans normally have two copies of this chromosome, as they normally do with all chromosomes. Chromosome 9 spans about 138 million base pairs of nucleic acids (the building blocks of DNA) and represents between 4.0 and 4.5% of the total DNA in cells.

Genes

Number of genes

These are some of the gene count estimates of human chromosome 9. Because researchers use different approaches to genome annotation, their predictions of the number of genes on each chromosome varies (for technical details, see gene prediction). 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.[5]

Cytogenetic band

G-banding ideograms of human chromosome 9

G-banding ideogram of human chromosome 9 in resolution 850 bphs. Band length in this diagram is proportional to base-pair length. This type of ideogram is generally used in genome browsers (e.g. Ensembl, UCSC Genome Browser).

G-banding patterns of human chromosome 9 in three different resolutions (400,[12] 550[13] and 850[4]). Band length in this diagram is based on the ideograms from ISCN (2013).[14] This type of ideogram represents actual relative band length observed under a microscope at the different moments during the mitotic process.[15]
