A Fully 59-CG-39 but Not a 59-CCGG-39 Methylated Late Frog Virus 3 Promoter Retains Activity
Several lines of evidence demonstrate that the DNA of the iridovirus frog virus 3 (FV3) is methylated in all 5*-CG-3* sequences both in virion DNA and in the intracellular viral DNA at late times after infection. The 5-methyldeoxycytidine residues in this viral DNA occur exclusively in 5*-CG-3* dinucleotide positions. We have cloned and determined the nucleotide sequence of the L1140 gene and i...
متن کاملDouble-Strand Break Repair in Bacteriophage T4: Recombination Effects of 39–59 Exonuclease Mutations
The role of 39–59 exonucleases in double-strand break (DSB)-promoted recombination was studied in crosses of bacteriophage T4, in which DSBs were induced site specifically within the rIIB gene by SegC endonuclease in the DNA of only one of the parents. Frequency of rII recombinants was measured in two-factor crosses of the type i 3 ets1, where ets1 designates an insertion in the rIIB gene carry...
متن کاملExecutive functions and sustained attention: Comparison between age groups of 19-39 and 40-59 years old
Few studies involving the cognition of middle-aged adults are available in the international literature, particularly investigating the process of cognitive aging, executive components and attention. Objectives The aim of this study was to investigate whether there are differences in performance on neuropsychological tasks of executive functions and sustained attention between two age groups....
متن کاملOscillating kissing stem–loop interactions mediate 59 scanning-dependent translation by a viral 39-cap-independent translation element
The 39-untranslated regions (UTRs) of a group of novel uncapped viral RNAs allow efficient translation initiation at the 59proximal AUG. A well-characterized model is the Barley yellow dwarf virus class of cap-independent translation elements (BTE). It facilitates translation by forming kissing stem–loops between the BTE in the 39-UTR and a BTE-complementary loop in the 59-UTR. Here we investig...
متن کامل59 . 2 / G . Ward 59 . 2 : Defining Dynamic Range
We introduce a new metric for dynamic range of displays that closely corresponds with human perception in practical settings. The Number of Distinguishable Grays is a count of the visible luminance steps from the deepest black to the brightest white a display produces under known ambient conditions.
