1. Specific Disulfide Bond Formation Directed by Peptide Nucleic Acids
In this study, we successfully demonstrated a strategy for specific disulfide bond formation by hybridization of two complementary peptide nucleic acid strands. Peptides were linked to the pair of complementary peptide nucleic acids by native chemical ligation, respectively, and base pairing drove the two peptides into close proximity for interchain disulfid

2. Recent developments in nucleic acid based techniques for use in rumen manipulation
Metodologias baseadas na análise de ácidos nucléicos, que possam ser utilizadas para caracterizar comunidades microbianas complexas, sem a necessidade da incubação de amostras, têm sido empregadas atualmente, de forma rotineira, em estudos de nutrição de ruminantes. Os métodos convencionais, dependentes do cultivo microrganismos ruminais (bactérias

3. Efeito dos diferentes níveis de nucleotídeos em frangos de corte alimentados com probióticos / Effect of the different nucleotides levels in broiler chickens fed with probitics
The objective of this experiment was to evaluate the influence of different nucleotides levels in the rations of broilers containing probiotics on response of the birds and its influence on the performance. Birds were allocated in a randomized experimental design with five replications of each treatment. It was used 1,050 chicks of a day of age, males, distr

4. Glutamine and glutamate as vital metabolites
Glucose is widely accepted as the primary nutrient for the maintenance and promotion of cell function. This metabolite leads to production of ATP, NADPH and precursors for the synthesis of macromolecules such as nucleic acids and phospholipids. We propose that, in addition to glucose, the 5-carbon amino acids glutamine and glutamate should be considered to b

5. Nucleic acid duplexes incorporating a dissociable covalent base pair
We have used molecular modeling techniques to design a dissociable covalently bonded base pair that can replace a Watson-Crick base pair in a nucleic acid with minimal distortion of the structure of the double helix. We introduced this base pair into a potential precursor of a nucleic acid double helix by chemical synthesis and have demonstrated efficient no

6. Nucleic acid fragmentation on the millisecond timescale using a conventional X-ray rotating anode source: application to protein–DNA footprinting
Nucleic acid fragmentation (footprinting) by ·OH radicals is used often as a tool to probe nucleic acid structure and nucleic acid–protein interactions. This method has proven valuable because it provides structural information with single base pair resolution. Recent developments in the field introduced the ‘synchrotron X-ray footprinting’ method, wh

7. A design for computer nucleic-acid-sequence storage, retrieval, and manipulation
We have designed and built a data-base system for the storage of nucleic-acid sequences. The system consists of a data base (“the library”) and software that manages and provides access to that data base (“the Librarian”).

8. Analysis of conformational parameters in nucleic acid fragments. II. Co-crystal complexes of nucleic acid bases.
Studies have been made of conformational parameters in co-crystal complexes and compounds of nucleic acid bases in which there is the possibility of formation of hetero-base-pairs. Using published data extracted from the Cambridge structural database, a total of 37 base-pairs were found, of which 25 were hetero-pairs and 12 homo-pairs. These base-pairs were

9. 3DNA: a software package for the analysis, rebuilding and visualization of three-dimensional nucleic acid structures
We present a comprehensive software package, 3DNA, for the analysis, reconstruction and visualization of three-dimensional nucleic acid structures. Starting from a coordinate file in Protein Data Bank (PDB) format, 3DNA can handle antiparallel and parallel double helices, single-stranded structures, triplexes, quadruplexes and other complex tertiary folding

10. BASES OF THE NUCLEIC ACID OF FOWLPOX VIRUS AND HOST DEOXYRIBONUCLEIC ACID
Randall, Charles C. (University of Mississippi School of Medicine, Jackson), Lanelle G. Gafford, and Robert W. Darlington. Bases of the nucleic acid of fowlpox virus and host deoxyribonucleic acid. J. Bacteriol. 83:1037–1041. 1962.—The nucleic acid of fowlpox virus obtained from purified inclusions was identified as deoxyribonucleic acid (DNA). The base

11. Genetic Relationship Among Bacteria Classified as Vibrios1
Genetic relatedness among six bacterial strains currently classified as vibrios was determined by biochemical tests, deoxyribonucleic acid base composition analysis, and the detection of nucleic acid homology by the membrane filter method. Varying degrees of genetic homology existed among vibrios having similar base compositions. The bovine isolate which had

Bacteriol. 87:1397–1401. 1964.—The biosynthesis of mycobacillin, a cyclic polypeptide antifungal antibiotic, was studied in relation to the effect of chloramphenicol, 6-azathymine, and 5-bromoura
