A genome is all the [[hereditary]] information held by an [[organism]]. This includes both expressed and non-expressed genetic [[information]]. In most organisms, it is stored in [[DNA]]; however, [[retrovirus]]es store it in [[RNA]], another type of [[nucleic acid]].  The information is encoded in the form of triplets of organic molecules called [[nucleotides]].

# the [[Nucleus|nuclear]] genome: Information found inside the nucleus of a cell.

# the [[Mitochondria|mitochondrial]] genome: Information found in the [[mitochondria]]<ref>http://www.medterms.com/script/main/art.asp?articlekey=3580</ref> (this separate genome is used as evidence for the [[endosymbiotic hypothesis]], although it can also be explained by creationist models).

In addition, organisms often inherit other material from their parents, such as proteins, RNA molecules, and other chromosomal factors like methyl groups attached to certain base pairs. These are regarded as the purview of [[epigenetics]].

Genomes of other species have been recorded as well, such as mice,<ref>http://www.ncbi.nlm.nih.gov/genome/guide/mouse/</ref> chimpanzees<ref>http://www.nature.com/nature/focus/chimpgenome/index.html</ref> and yeast.<ref>http://www.yeastgenome.org/</ref>  The mouse genome sequence from the C57BL/6J strain has about 30,000 genes, and 99% of them have direct counterparts in humans.<ref>http://www.nature.com/nature/journal/v420/n6915/full/420509a.html</ref>

The chimpanzee represented the first non-human primate sequenced. The differences in the chimpanzee and human genomes are small, with 99% of the DNA sequence preserved. <ref>http://www.nih.gov/news/pr/aug2005/nhgri-31.htm</ref> The differences can be classified in terms of differences in local single nucleotide substitutions, insertions, deletions and repetitions of sequences.  A relatively large number of difference between the chimpanzee and human genomes are not due to substitutions.<ref>http://207.210.67.162/~striz/docs/chimpc.pdf</ref> When this is taken into account, humans and chimpanzees still share 96% of their sequence, and are genetically closer than rats and mice.<ref>http://www.nih.gov/news/pr/aug2005/nhgri-31.htm</ref>
