5 Must Know Facts For Your Next Test

  1. rRNA is essential for the proper alignment of mRNA and tRNAs within the ribosome during translation.
  2. There are three main types of rRNA in prokaryotes: 16S, 23S, and 5S.
  3. The rRNA genes are highly conserved across different species, making them useful for phylogenetic studies.
  4. Eukaryotic ribosomes have four types of rRNA: 18S, 5.8S, 28S, and 5S.
  5. rRNA catalyzes the formation of peptide bonds between amino acids during protein synthesis.
