5S rRNA sequences from eight basidiomycetes and fungi imperfecti
Nucleic Acids Research
|November 11, 1983
Abstract:
The 5S rRNA sequences from the basidiomycetes or fungi imperfecti Rhizoctonia crocorum, Rhizoctonia hiemalis, Exobasidium vaccinii, Trichosporon oryzae, Tilletia controversa, Tilletiaria anomala, Dacrymyces deliquescens and Coprinus radiatus were determined. With the exception of Exobasidium, these sequences conform to the association previously found between septal pore type and sequence. The sequence from the supposed ascomycete anamorph Rhizotonia hiemalis clearly is allied with basidiomycete sequences.

Overview
RNA Splicing
Splicing is the process by which eukaryotic RNA is edited before its translation into protein. The RNA strand transcribed from eukaryotic DNA is called the primary transcript. The primary transcripts that become mRNAs are called precursor messenger RNAs (pre-mRNAs). Eukaryotic pre-mRNA contains alternating sequences of exons and introns. Exons are nucleotide sequences that code for proteins, whereas introns are the non-coding regions. In RNA splicing, introns are removed and exons are bonded...
Ribosomal RNA Synthesis
Ribosome synthesis is a highly complex and coordinated process involving more than 200 assembly factors. The synthesis and processing of ribosomal components occurs not only in the nucleolus but also in the nucleoplasm and the cytoplasm of eukaryotic cells.
Ribosome biogenesis begins with the synthesis of 5S and 45S pre-rRNAs by distinct RNA polymerases. The primary transcripts are extensively processed and modified before they are bound and folded by ribosomal proteins and assembly factors,...
