Gene prediction
Gene prediction
Gene prediction or gene finding is the process of identifying the regions of genomic DNA that encode genes. This includes protein-coding genes as well as RNA genes, but may also include prediction of other functional elements such as regulatory regions. Gene finding is one of the first and most important steps in understanding the genome of a species once it has been sequenced.
Pronunciation
- Gene: /dʒiːn/
- Prediction: /prɪˈdɪkʃən/
Etymology
The term "gene" was coined by the Danish botanist, plant physiologist and geneticist Wilhelm Johannsen in 1909. It is derived from the Greek word "genos" which means "race, kind". The term "prediction" comes from the Latin "praedictio" which means "foretelling".

- Genes: A unit of heredity which is transferred from a parent to offspring and is held to determine some characteristic of the offspring.
- RNA genes: Genes that encode RNA molecules that function directly, rather than through the production of proteins.
- Regulatory regions: A segment of DNA where regulatory proteins such as transcription factors bind preferentially.
- Genome: The complete set of genes or genetic material present in a cell or organism.
