NUCLEOTIDE COMPOSITION OF RIBONUCLEIC ACID FROM NEUROSPORA CRASSA. 1963

H HENNEY, and R STORCK

Henney, H. (The University of Texas, Austin) and R. Storck. Nucleotide composition of ribonucleic acid from Neurospora crassa. J. Bacteriol. 85:822-826. 1963.-The nucleotide composition of total, ribosomal, and soluble ribonucleic acid (RNA) from the conidia and the hyphae of Neurospora crassa was determined. The corresponding RNA classes from the two morphological types had the same base ratio. Total, ribosomal, and soluble RNA from hyphae contained, respectively, 51.0, 50.2, and 61.6% guanylic acid (G) plus cytidylic acid (C), and from conidia, 50.6, 49.9, and 62.1%. The proportion of nucleotides in ribosomal RNA was in close agreement with that reported for ribosomal RNA from other organisms. Soluble RNA contained 2.8% pseudouridylic acid, 36.0% C, and 25.5% G, and differed from soluble RNA from other sources in its high C content. Centrifugation of purified RNA from conidia and hyphae, through a linear sucrose-density gradient, yielded identical sedimentation profiles.

UI	MeSH Term	Description	Entries
D009491	Neurospora	A genus of ascomycetous fungi, family Sordariaceae, order SORDARIALES, comprising bread molds. They are capable of converting tryptophan to nicotinic acid and are used extensively in genetic and enzyme research. (Dorland, 27th ed)	Neurosporas
D009492	Neurospora crassa	A species of ascomycetous fungi of the family Sordariaceae, order SORDARIALES, much used in biochemical, genetic, and physiologic studies.	Chrysonilia crassa
D009711	Nucleotides	The monomeric units from which DNA or RNA polymers are constructed. They consist of a purine or pyrimidine base, a pentose sugar, and a phosphate group. (From King & Stansfield, A Dictionary of Genetics, 4th ed)	Nucleotide
D012270	Ribosomes	Multicomponent ribonucleoprotein structures found in the CYTOPLASM of all cells, and in MITOCHONDRIA, and PLASTIDS. They function in PROTEIN BIOSYNTHESIS via GENETIC TRANSLATION.	Ribosome
D012313	RNA	A polynucleotide consisting essentially of chains with a repeating backbone of phosphate and ribose units to which nitrogenous bases are attached. RNA is unique among biological macromolecules in that it can encode genetic information, serve as an abundant structural component of cells, and also possesses catalytic activity.

D012335	RNA, Ribosomal	The most abundant form of RNA. Together with proteins, it forms the ribosomes, playing a structural role and also a role in ribosomal binding of mRNA and tRNAs. Individual chains are conventionally designated by their sedimentation coefficients. In eukaryotes, four large chains exist, synthesized in the nucleolus and constituting about 50% of the ribosome.
