RIBOSOMAL RNA GENES Meaning and
Definition
-
Ribosomal RNA (rRNA) genes are sections of DNA in the genome of an organism that contain the genetic instructions for the production of ribosomal RNA molecules. Ribosomal RNA is a crucial component of ribosomes, the cellular structures responsible for protein synthesis. These genes are essential for the functioning of living cells, as they play a vital role in translation, which is the process through which genetic information in mRNA is converted into proteins.
Ribosomal RNA genes are highly conserved in most organisms, meaning they are relatively unchanged across different species. They exist in multiple copies within the genome, and each copy is referred to as a ribosomal RNA gene locus. These loci can be found on one or multiple chromosomes, depending on the organism.
The process of transcription involves the synthesis of pre-rRNA molecules from these genes. These pre-rRNAs are then modified and processed in a series of steps to form mature rRNA molecules that are incorporated into ribosomal subunits. Different types of rRNA genes code for different parts of the ribosome, such as the 18S, 5.8S, and 28S rRNA molecules found in eukaryotes.
Ribosomal RNA genes are widely studied in biology and genetics due to their essential role in protein synthesis. They are often used as molecular markers in phylogenetic studies to understand evolutionary relationships between different organisms.
