Chromatin- and nuclei-directed ribonucleic Acid synthesis in sugar beet root.
The synthesis of RNA by chromatin-bound RNA polymerase prepared from sugar beet (Beta vulgaris) root tissue is completely dependent on the presence of a divalent metal (Mg(2+) or Mn(2+)) and the presence of four ribonucleoside triphosphates. Accumulation of labeled acid-insoluble product is inhibited by the addition of RNase and actinomycin D to the reaction. When beet root slices are washed fo...
متن کاملEnzymatic Synthesis of Ribonucleic Acid. Iv. the Deoxyribonucleic Acid-directed Synthesis of Complementary Cytoplasmic Ribonucleic Acid Components.
The ribonucleic acid product formed by ribonucleic acid polymerase resembles its deoxyribonucleic acid template in base composition and in base sequence (l-6). The reaction in vitro results in the synthesis of RNA chains which are complementary to both DNA strands (6). Evidence for this originates from the formation of highly ordered RNA structures when the RNA polymerase product is annealed wi...
متن کاملDeoxyribo ucleic acid-directed synthesis of ribonucleic acid by an enzyme from Escherichia coli.
l’rotein structure is under genetic control;’-3 yet the precise mechanism by which DNA$ influences the formation of specific amino acid sequences in proteins is unknown. Several years ago, it was discovered that infection of Escherichia coli with certain virulent bacteriophages induces the formation of an RNA fraction possessing both a high metabolic turnover rate and a base composition corresp...
متن کاملEnzymatic Synthesis of Ribonucleic Acid
The discovery of enzymes which catalyze the deoxyribonucleic acid-dependent synthesis of ribopolynucleotides (l-6) stimulated an immediate inquiry into the role played by DNA in thisunique reaction. The speculation that DNA might serve as a template for the polymerization of ribonucleotides into a complementary ribonucleic acid molecule was confirmed by studies from a number of different groups...
متن کاملThe Enzymatic Synthesis of Ribonucleic Acid in Animal Tissue. I. the Deoxyribonucleic Acid-directed Synthesis of Ribonucleic Acid as Catalyzed by an Enzyme Obtained from Bovine Lymphosarcoma Tissue.
The enzyme RNA polymerase can be isolated from normal bovine lymph nodes as well as from bovine lymphosarcoma. The characteristics of the enzyme, obtained from the 2 sources, are similar. The specific activity of the enzyme, both in the crude extract and in the partially purified preparation, is twice as high in the neoplastic tissue.
