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 DNA annotation or genome annotation is the process of identifying the locations of genes and all of the coding regions in a genome and determining what those genes do. An annotation (irrespective of the context) is a note added by way of explanati ...
