DNA DEPENDENT RNA POLYMERASE III Meaning and
Definition
-
DNA-dependent RNA polymerase III (RNAP III) is a specialized enzyme responsible for transcribing DNA into RNA molecules. It is one of three types of RNA polymerases found in eukaryotic cells, along with RNA polymerase I and RNA polymerase II. Eukaryotic RNAP III is responsible for synthesizing small non-coding RNAs, such as transfer RNA (tRNA), 5S ribosomal RNA (rRNA), and small nuclear RNA (snRNA).
DNA-dependent RNA polymerase III operates through a process called transcription, which involves the synthesis of RNA molecules using a DNA template. This enzyme recognizes specific DNA sequences known as promoters, which are located upstream of the genes that encode the RNA molecules it transcribes. Once bound to the promoter, RNAP III unwinds the DNA double helix and initiates the synthesis of RNA by adding nucleotides that are complementary to the DNA template strand.
RNAP III differs from RNA polymerase I and II in terms of the genes it transcribes and the types of RNA produced. While RNA polymerase I mainly synthesizes precursor rRNA molecules for ribosome assembly, and RNA polymerase II transcribes protein-coding genes, RNAP III is primarily responsible for generating non-coding RNAs that perform various functions in the cell.
In summary, DNA-dependent RNA polymerase III is an essential enzyme involved in the transcription of specific DNA sequences into various types of small non-coding RNA molecules, such as tRNA, 5S rRNA, and snRNA.
