ANTISENSE RNA Meaning and
Definition
-
Antisense RNA is a specific type of RNA molecule that plays a critical role in gene regulation. It is a single-stranded RNA molecule that is complementary in sequence to a target messenger RNA (mRNA) molecule. The antisense RNA molecule is transcribed from the opposite DNA strand to the target mRNA, hence the term "antisense."
The main function of antisense RNA is to inhibit gene expression by preventing the production of a specific protein. When an antisense RNA molecule binds to its complementary target mRNA, it can form a double-stranded structure that prevents the target mRNA from being translated into protein by ribosomes. This binding essentially masks the target mRNA, making it inaccessible to the cell's translation machinery.
Antisense RNA has been recognized as an important molecular tool for researchers studying gene function and regulation. Scientists can design and use synthetic antisense RNA molecules to specifically target and silence the expression of a particular gene of interest. This technique, known as RNA interference (RNAi), has revolutionized genetic research and has potential applications in therapeutic interventions for diseases caused by overactive or faulty genes.
Overall, antisense RNA serves as a critical player in the intricate regulatory mechanisms of gene expression. By blocking the translation of specific mRNA molecules, it helps control protein levels and influences cellular processes, such as development, differentiation, and response to environmental stimuli.

Etymology of ANTISENSE RNA
The term "antisense RNA" is composed of two parts: "anti-" and "sense RNA".1. "Sense" comes from the Latin word "sensus", which means "meaning" or "perception". In molecular biology, "sense" refers to a DNA or RNA sequence that has the same base sequence as the mRNA (messenger RNA) that will be translated into a protein. Sense RNA or sense strand is the complementary strand to the antisense RNA in a double-stranded RNA molecule.2. "Anti-" is a prefix derived from the Greek word "anti", meaning "opposite" or "against". In the context of molecular biology, "anti-" refers to a molecule or sequence that is complementary to another molecule or sequence. In the case of antisense RNA, it refers to RNA that is complementary to the sense RNA or sense strand, meaning its base pairings are opposite to those of the sense RNA.
