We report the nucleotide sequence of the Group IV RNA bacteriophage SP. The entire sequence is 4276 nucleotides long. Four cistrons have been identified by comparison with the related Group III phage Q beta. The maturation protein contains 449 amino acids, the coat protein contains 131 amino acids, the read-through protein contains 330 amino acids and the(More)
The "operon' theory of gene regulation, in which protein repressor molecules bind to the operator site of a gene to prevent its transcription, is now well established. Recently, however, cases have been discovered in which gene expression is regulated by complementary RNA molecules that are able to bind to the transcripts of particular genes and(More)
We evaluate the short term forecasting performance of methods that systematically incorporate high frequency information via covari-ates. Our results indicate that including timely intra-period data into the forecasting process results in significant gains in predictive accuracy compared to relying exclusively on low frequency aggregates.

The effect of heat stress (38 degrees C) on the content of octopamine (OA) and 20-hydroxyecdysone (20HE) was studied under normal and stressful conditions in adult flies of Drosophila virilis lines contrasting in the level of the juvenile hormone (JH). The wild-type flies (line 101) exhibited a pronounced sex dimorphism for the content of both OA and 20HE,(More)
In order to clarify the taxonomic status of an RNA coliphage, MX1 (a serological intermediate between groups III and IV), we examined (i) read-through protein synthesis in a cell-free protein-synthesizing system, (ii) the peptide map of the coat protein and (iii) the RNA sequence in the 3'-terminal region of MX1 RNA. We found that the characteristics of MX1(More)
