Preribosomal RNA - Wikipedia
Pre-rRNA comprise three main sizes; 37S (yeast), 40S (Xenopus) and 45S (mammals). In a series of steps, nearly 80 ribosomal proteins assemble with the pre-rRNA. During transcription …
What is the difference between 47s and 45s rRNA in humans?
Jun 30, 2018 · Schematic representation of the human pre-rRNA processing pathways. The 47S pre-rRNA is converted to the 45S pre-rRNA following the initial cleavages at sites A′ in the 5′ …
Ribosomal RNA regulates chromosome clustering during mitosis
May 31, 2022 · In particular, pre-rRNAs such as 45S, 32S, and 30S are highly enriched on mitotic chromosomes. Immediately following nucleolus disassembly in mitotic prophase, rRNAs are …
