Genes are the basic physical and functional units of heredity. They are molecular [[information]] that ultimately determine the traits possessed by any organism. A gene is a specific sequence of nucleotide bases on the DNA molecule ([[Deoxyribonucleic acid]]). The sequence of nucleotides specifies the information required for constructing [[proteins]], which provide the structural components of cells and tissues as well as [[enzymes]] for essential biochemical reactions. Typically the products of several genes are assembled to make a functional [[protein]]. Likewise a single gene can be involved with the production of several different proteins.
==Pseudogenes==
: ''Main Article: [[{{Artículo principal|Pseudogenes]]''}}
Pseudogenes are nonfunctional errors rarely with a functional gene counterpart and rarely able to be [[Transcription|transcribed]]. Pseudogenes are dependent on an [[organisms]] lifestyle and living relationships as well as rates of [[genome]] duplication and [[mutation]]. Found in three [[Taxonomy#Kingdoms|kingdoms of life]] primarily study within mainstream evolutionary science has been focused on the similar loci of [[primate]] and [[homo sapien]] pseudogenes in order to further establish humans common ancestry.<ref name=loc>[http://genome.cshlp.org/content/13/12/2541.long ''Millions of Years of Evolution Preserved: A Comprehensive Catalog of the Processed Pseudogenes in the Human Genome''] By Zhaolei Zhang, Paul M.
