Role of RNA Polymerase III in Transcription in Eukaryotes
RNA polymerase III (Pol III) is one of the three types of RNA polymerases present in eukaryotic cells. It is responsible for transcribing several types of small RNAs that play important roles in gene expression and protein synthesis. The following are the details of the role of RNA polymerase III in transcription in eukaryotes:
Transcription of tRNA Genes
Pol III transcribes genes that encode transfer RNAs (tRNAs). tRNAs are small RNA molecules that serve as adapters between mRNA and amino acids during protein synthesis. Since there are 20 different amino acids, there are 20 different types of tRNAs. Pol III transcribes each tRNA gene as a separate transcript.
Transcription of 5S rRNA Genes
Pol III also transcribes genes that encode 5S ribosomal RNA (rRNA). 5S rRNA is a component of the large ribosomal subunit in eukaryotic cells. It plays a role in stabilizing the overall structure of the ribosome.
Transcription of snRNA Genes
Pol III transcribes a subset of small nuclear RNAs (snRNAs), which are involved in pre-mRNA splicing. The snRNAs transcribed by Pol III include U6, 7SK, and the 7SL RNA component of the signal recognition particle (SRP).
Overall, Pol III is responsible for transcribing several small RNA molecules that play critical roles in gene expression and protein synthesis. These small RNAs are essential for the proper functioning of cells and organisms.
