RIBOSOMAL RNA GENE Meaning and
Definition
-
Ribosomal RNA Gene is a segment of DNA that codes for ribosomal RNA (rRNA) molecules. The ribosomes, consisting of protein and rRNA, are essential cellular structures responsible for protein synthesis. The ribosomal RNA gene acts as a template for the synthesis of ribosomal RNA, which combines with proteins to form ribosomes.
The ribosomal RNA gene is found in the genome of most living organisms, including bacteria, archaea, and eukaryotes. It is typically present in multiple copies, known as gene clusters or rDNA (ribosomal DNA) repeats. These repeats can be arranged in tandem arrays and are commonly found in specific regions of the chromosomes known as nucleolar organizer regions.
The ribosomal RNA gene is transcribed by the enzyme RNA polymerase I into a long precursor molecule called the pre-rRNA, which undergoes several processing steps to produce mature rRNAs. These rRNAs are then incorporated into ribosomes, which play a crucial role in protein synthesis by decoding messenger RNA sequences and catalyzing the formation of peptide bonds between amino acids.
The ribosomal RNA gene is highly conserved across different species, indicating its essential role in cellular processes. It serves as a useful marker for phylogenetic studies and is often used in the identification and classification of organisms. Moreover, changes or mutations in the ribosomal RNA gene can have significant impacts on the function and structure of ribosomes, leading to various diseases and disorders.
