ribosomal RNA
Let an agent explain ribosomal RNA by type, structure, function, gene organisation and research uses such as microbial identification.
Research draft, second pass
A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify. Unreviewed either way.

Purpose and description
Let an agent explain ribosomal RNA by type, structure, function, gene organisation and research uses such as microbial identification.
The RNA component of ribosomes, which forms their structural core and catalyses peptide bond formation; prokaryotes have 5S, 16S and 23S rRNAs and eukaryotes have 5S, 5.8S, 18S and 28S rRNAs, and 16S rRNA gene sequencing is widely used to identify bacteria.
What it is for: Protein synthesis, microbiology and evolutionary studies.
It can be explain rRNA types and ribosome structure; describe the catalytic role of rRNA; use 16S rRNA sequencing for identification; find rRNA sequence databases.
