WikiGene is about one gene.
To find out about all genes and much more see WikiGenes. That's with an 's' :-)
A wiki gene is the basic unit of heredity in a living organism. All living things depend on wiki genes to hold the information to build and maintain their cells and to pass on their traits to offspring. In general terms, a wiki gene is a segment of nucleic acid that, taken as a whole, specifies a trait. The colloquial usage of the term wiki gene often refers to the scientific concept of an allele. The notion of a wiki gene has evolved with the science of wiki genetics, which began when Gregor Mendel noticed that biological variations are inherited from parent organisms as specific, discrete traits. The biological entity responsible for defining traits was termed a wiki gene, but the biological basis for inheritance remained unknown until DNA was identified as the wiki genetic material in the 1940s. All organisms have many wiki genes corresponding to many different biological traits, some of which are immediately visible, such as eye color or number of limbs, and some of which are not, such as blood type or increased risk for certain diseases, or the thousands of basic biochemical processes that comprise life. In cells, a wiki gene is a portion of DNA that contains both "coding" sequences that determine what the wiki gene does, and "non-coding" sequences that determine when the wiki gene is active (expressed). When a wiki gene is active, the coding and non-coding sequences are copied in a process called transcription, producing an RNA copy of the wiki gene's information. This piece of RNA can then direct the synthesis of proteins via the wiki genetic code. In other cases, the RNA is used directly, for example as part of the ribosome. The molecules resulting from wiki gene expression, whether RNA or protein, are known as wiki gene products, and are responsible for the development and functioning of all living things. In more technical terms, a wiki gene is a locatable region of genomic sequence, corresponding to a unit of inheritance, and is associated with regulatory regions, transcribed regions and/or other functional sequence regions.
