Ribosomal RNA (rRNA)
from class: Microbiology Definition Ribosomal RNA (rRNA) is a type of RNA that, along with proteins, makes up the ribosomes. Ribosomes are the cellular structures where protein synthesis occurs.
congrats on reading the definition of ribosomal RNA (rRNA) . now let's actually learn it.
Predict what's on your test 5 Must Know Facts For Your Next Test rRNA forms the core structural and functional components of ribosomes. There are three primary types of rRNA in prokaryotes: 16S, 23S, and 5S rRNA. In eukaryotes, the major rRNAs are 18S, 28S, 5.8S, and 5S. rRNA genes are highly conserved across different species due to their essential role in protein synthesis. The process of rRNA synthesis occurs in the nucleolus of eukaryotic cells. Review Questions What is the function of ribosomal RNA within the ribosome? How many types of rRNA are typically found in prokaryotic cells? Where does rRNA synthesis occur in eukaryotic cells? "Ribosomal RNA (rRNA)" also found in:
