COILED BODIES Meaning and
Definition
-
Coiled bodies are distinct structures found within the cell nucleus, specifically in the nucleoplasm, that consist of small, spherical and tightly coiled loops of DNA and protein complexes. Also known as Cajal bodies or coiled body-like structures, they were first identified by the Spanish neuroanatomist Santiago Ramón y Cajal in the late 19th century, who initially described them as perinuclear reticular structures.
These bodies are involved in a wide range of cellular functions, including transcription, processing, and modification of RNA molecules, as well as the assembly and modification of ribonucleoprotein complexes. They are particularly identified with their involvement in the biogenesis of small nuclear ribonucleoproteins (snRNPs), which are crucial components of the cellular machinery responsible for pre-mRNA splicing.
Coiled bodies are composed of a complex mixture of proteins and RNA molecules. Some of the predominant protein components include coilin, SMN (survival of motor neuron), and an array of RNA-binding proteins. They are dynamic structures that can vary in size, number, and composition depending on the cellular conditions and stage of the cell cycle.
Overall, coiled bodies play a crucial role in the regulation of gene expression and RNA processing in eukaryotic cells. Their study continues to be an active area of research, aiming to uncover their precise functions and unravel their intricate role in cellular processes.

Etymology of COILED BODIES
The term "Coiled Bodies" is not a widely recognized or commonly used term in English. Therefore, it does not have a specific etymology. However, if we analyze the individual words within the term, we can understand their general meanings.
1. Coiled: The word "coiled" is the past participle of the verb "coil", which means to wind or twist into a continuous or spiral shape. The origin of "coil" can be traced back to the Old French word "coillir", meaning "to collect" or "to wind up". In turn, this ties back to the Latin word "coligere", which means "to gather" or "to bring together".
2. Bodies: The word "bodies" is the plural form of the noun "body". Its etymology stems from the Old English word "bodig", meaning the physical structure of a living organism.
