The Relationship between Satellite Deoxyribonucleic Acid, Ribosomal Ribonucleic Acid Gene Redundancy, and Genome Size in Plants.
The buoyant density of ribosomal DNA is similar in species with or without satellite DNA, and in all species examined was distinguishable from that of the satellite DNA. In melon tissues (Cucumus melo) the percentage satellite DNA is not correlated with the percentage hybridization to ribosomal RNA. Satellite DNA sequences do not appear to be dispersed between those coding for ribosomal RNA. Th...
متن کاملLocalization of deoxyribonucleic acid complementary to ribosomal ribonucleic acid and preribosomal ribonucleic acid in the nucleolus of rat liver.
The fraction and distribution of DNA complementary to ribosomal RNA and preribosomal RNA was investigated by the technique of molecular hybridization with the DNA of isolated nucleoli and nuclei of rat liver. Nuclear DNA complementary to ribosomal 18 S RNA and 28 S RNA was 0.014% and 0.032%, respectively. Nucleolar DNA complementary to ribosomal 18 S RNA and 28 S RNA was 0.10% and 0.22%, respec...
متن کاملThe role of deoxyribonucleic acid in ribonucleic acid synthesis. I. The purification and properties of ribonucleic acid polymerase.
It has become evident that several enzymatic reactions exist which lead to the incorporation of the mononucleotide moiety of the ribonucleoside triphosphates into ribonucleic acid (1). The first of these enzymes to be characterized catalyzes the addition of cytosine 5’-phosphate and adenosine 5’-phosphate to the nucleoside terminal end of soluble ribonucleic acid (2,3). The product of this reac...
متن کاملIsolation and characterization of an endonuclease from Escherichia coli specific for ribonucleic acid in ribonucleic acid-deoxyribonucleic acid hybrid structures.
A ribonuclease which degrades RNA specifically in RNA. DNA hybrid structures has been purified X00-fold from Escherichia co2i B and ZOO-fold from E. coli strain DllO pot A1, endo I-, fhy-). For maximal activity, the enzyme requires MgZ+ and the presence of a sulfhydryl reagent. The enzyme is capable of digesting more than 95% of the RNA in RNA .DNA hybrids to acid-soluble products. The products...
متن کاملThe Enzymatic Methylation of Ribonucleic Acid and Deoxyribonucleic Acid. Vii. the Methylation of Ribonucleic Acid.
Preceding publications from this laboratory have shown that the methylation of soluble ribonucleic acid is catalyzed by at least six discrete enzymes (l-3) which have been purified from extracts of Escherichia coli W. Two of these enzyme preparations catalyze the formation of l-methylguanine residues in SRNA,1 while a third produces 7-methylguanine. The others catalyze the methylation of uracil...
