Quick Reference

The giant RNA molecule transcribed from a ribosomal RNA gene (q.v.). In Drosophila, it is 38S, in Xenopus it is 40S, and in HeLa cells it is 45S. After transcription, preribosomal-RNA is cleaved one or more times to generate the 5.8S, 18S, and 28S rRNAs that become components of ribosomes.
