intron etymology

Etymology and Meaning:

The word "intron" is derived from:

• int- (Latin prefix meaning "within")
• tron- (Greek term "tronos" meaning "throne")

An intron is thus literally a "throne within" a gene.

Origin:

The term "intron" was first used in 1977 by Walter Gilbert to describe non-coding sequences within a gene that were removed during RNA splicing.

Definition:

An intron is a non-coding region of DNA within a gene that is transcribed into RNA but is subsequently removed through RNA splicing. Introns are typically located between exons, which are the coding regions of a gene.

Characteristics:

• Typically much longer than exons
• Do not contain any information that is translated into protein
• Are highly variable in sequence and length among different genes
• May contain regulatory elements that control gene expression
