Chromosome 17 is one of the 23 pairs of
chromosomes in
humans. People normally have two copies of this chromosome. Chromosome 17 spans more than 84 million
base pairs (the building material of
DNA) and represents between 2.5 and 3% of the total DNA in
cells.
Chromosome 17 contains the
Homeobox B gene cluster.
Genes
Number of genes
The following are some of the gene count estimates of human chromosome 17. 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). The most conservative estimate, from
CCDS, represents a lower bound on the total number of human protein-coding genes.[4]
G-banding ideogram of human chromosome 17 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 17 in three different resolutions (400,[12] 550[13] and 850[3]). 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]
