ribosomal RNA genes

Ribosomal RNA (rRNA) genes are segments of DNA that contain the instructions for making rRNA, a vital component of ribosomes—the cell’s protein factories. These genes are highly conserved and present in multiple copies, ensuring enough rRNA is produced for efficient protein synthesis. rRNA molecules help assemble amino acids into proteins by providing a structural framework and catalytic activity within the ribosome. Studying these genes helps scientists understand genetic organization and evolutionary relationships across species, as rRNA sequences are often used for identifying and classifying organisms.
