Chromosome 3
Chromosome 3 is one of the 23 pairs of chromosomes in humans. People normally have two copies of this chromosome. Chromosome 3 spans more than 201 million base pairs and represents about 6.5 percent of the total DNA in cells.
Genes
Number of genes
The following are some of the gene count estimates of human chromosome 3. Because researchers use different approaches to genome annotation their predictions of the number of genes on each chromosome varies. Among various projects, the collaborative consensus coding sequence project takes an extremely conservative strategy. So CCDS's gene number prediction represents a lower bound on the total number of human protein-coding genes.| Estimated by | Protein-coding genes | Non-coding RNA genes | Pseudogenes | Source | Release date |
