Abstract

This report is a translation of an article in the Russian Language periodical Priroda - "Biosynthesis of nucleic acids with the participation of proteins. Genetic transformation. Ionizing radiations and nucleic acids". Advanced methods of studying the cell. Research works of recent decades have established the very important role of the nucleic acids and their compounds with proteins (nucleoproteides) in a number of basic biological processes. The work in this direction is developing at exceptionally rapid rates and therefore an extremely timely event was the convoking of the First Conference on Nucleic Acids and Nucleoproteides, which had the aim of coordinating the research works carried out in various laboratories of the Soviet Union, of discussing their results, and of exchanging experience., Trans. of Priroda (Nature) (Russia) n5 p54-56 May 60.

Abstract

Template activity of nuclear pre-mRNA has been investigated in DNA-polymerase reaction. Active synthesis of DNA was demonstrated on pre-mRNA as a template in the absence of primer. A part of synthetic activity may be attributed to the traces of DNA present in the pre-mRNA preparation. Addition of oligo(dT)10 to the template stimulated the synthesis of DNA product due to transcription of heteropolymeric regions near the poly(A). The rate of DNA synthesis was different depending on the fraction of template used: the RNA extracted by hot phenol at 85 degrees showed higher template activity without adding of primer than the 65 degrees C fraction. On the contrary 65 degrees C pre-mRNA which is known to contain greater quantity of molecules with poly(A) at the 3'-end is more strongly stimulated by addition of oligo(dT). The nuclear RNA corresponding to the precursors of rRNAs extracted at 40 degrees C were not transcribed by the reverse transcriptase. The size of the DNA-product (about 7-8S in alkaline sucrose gradient) did not depend on the size of the template neither on the presence of oligo(dT)10 primer. The inhibition of the second DNA strand synthesis with actinomycin D had also no influence on the size of DNA-product.
