PROCESSED GENE Meaning and
Definition
-
Processed Gene:
A processed gene refers to a type of genetic material that has undergone a specific evolutionary mechanism known as retrotransposition. Retrotransposition is the process by which a pre-existing messenger RNA (mRNA) molecule is reverse-transcribed back into DNA and subsequently integrated into the genome, resulting in the creation of a new gene. This phenomenon primarily occurs in eukaryotic organisms and is characterized by the absence of introns in the processed gene.
Unlike regular genes, processed genes lack the non-coding regions (introns) typically observed in typical gene structures. This absence of introns is a distinguishing feature of processed genes. These genes are often derived from the mRNA transcripts of pre-existing genes. After being reverse transcribed into DNA by an enzyme called reverse transcriptase, these mRNA molecules are inserted into the genome at a new location.
Processed genes usually lack promoters and other regulatory elements necessary for gene expression. However, they can become functional if they acquire these regulatory elements through additional mutations or genetic events. Processed genes can have various roles, such as encoding functional proteins or serving as non-coding RNAs involved in regulatory processes.
Studying processed genes is essential for understanding the genetic evolution of organisms and the mechanisms that shape genomes. They provide insights into genome dynamics, gene duplication events, and the impact of retrotransposition on gene diversity.

Etymology of PROCESSED GENE
The term "Processed Gene" does not have a specific etymology because it appears to be a combination of two individual terms: "processed" and "gene". Here's the etymology of each term individually:
1. Processed:
The word "processed" is the past participle form of the verb "process", which is derived from the Old French word "proces" meaning "to go forth, advance, proceed". It entered English in the 15th century, initially referring to legal proceedings, and later took on a broader meaning related to the action of handling, treating, or preparing something.
2. Gene:
The word "gene" has its origin in the field of genetics and biology. It was coined by the Danish scientist Wilhelm Johannsen in 1909, based on the term "pangen", derived from the Greek word "pangen", meaning "all, entire".
