Intervening polyadenylate sequences in RNA transcripts of vesicular stomatitis virus. 1978

R C Herman, and S Adler, and R A Lazzarini, and R J Colonno, and A K Banerjee, and H Westphal

Purified and partially resolved vesicular stomatitis virus (VSV) messenger RNA has been annealed to the VSV genomic RNA and visualized in the electron microscope under conditions in which duplex regions have a wider image width than single-stranded RNA. The locations of the intercistronic boundaries between the messages have been mapped on the VSV genome. The contour of the double-stranded regions is occasionally interrupted by looped-out single-stranded RNA. The loops are comprised of post transcriptionally synthesized polyadenylate. Most of these structures are found at the intercistronic boundaries and covalently bridge adjacent message sequences. In this paper, we discuss the possible significance of these loops.

UI MeSH Term Description Entries
D009693 Nucleic Acid Hybridization Widely used technique which exploits the ability of complementary sequences in single-stranded DNAs or RNAs to pair with each other to form a double helix. Hybridization can take place between two complimentary DNA sequences, between a single-stranded DNA and a complementary RNA, or between two RNA sequences. The technique is used to detect and isolate specific sequences, measure homology, or define other characteristics of one or both strands.

D012333 RNA, Messenger RNA sequences that serve as templates for protein synthesis. Bacterial mRNAs are generally primary transcripts in that they do not require post-transcriptional processing. Eukaryotic mRNA is synthesized in the nucleus and must be exported to the cytoplasm for translation. Most eukaryotic mRNAs have a sequence of polyadenylic acid at the 3' end, referred to as the poly(A) tail. The function of this tail is not known for certain, but it may play a role in the export of mature mRNA from the nucleus as well as in helping stabilize some mRNA molecules by retarding their degradation in the cytoplasm.
