Abstract
Identification of several additional restriction endonuclease sites within the cellular substitution (amv) inserted into the avian myeloblastosis virus proviral genome has permitted us to isolate different regions of the amv sequence. These subsets of the avian myeloblastosis virus transforming gene have been cloned in the plasmid pBR322 and used as hybridization probes to investigate the topology of homologous (proto-amv) normal chicken DNA sequences. The results showed that the cellular proto-amv sequences in C/O chicken DNA are interrupted by at least one intervening sequence. A partial arrangement of the proto-amv sequences is presented.

Abstract
The tRNA(3) (Leu) gene from yeast contains an intervening sequence of 32 nucleotides not present in mature tRNA. This sequence is transcribed and subsequently removed during the maturation of the RNA. To probe the involvement of this region of the gene in transcription and processing of the pre-tRNA(3) (Leu), the yeast DNA was cloned in plasmid pBR322 and a 21-base-pair DNA fragment corresponding to the lac operator was inserted into the intervening sequence. Insertion was done at a cleavage site for the restriction endonuclease Hpa I that occurs 19/20 base pairs from the 5' end of the intervening sequence. The parent and modified plasmids were then transcribed in a Xenopus germinal vesicle extract. RNA-fingerprint analysis of the transcription products revealed that both the tRNA(3) (Leu) gene and its modified counterpart were accurately transcribed. Transcription products corresponding to mature tRNA(3) (Leu) and pre-RNA(3) (Leu) with the normal and lac-containing intervening sequence were identified. Precursors extended at their 5' and 3' ends were also present. Both parent and modified genes were transcribed efficiently, and the various products accumulated in similar amounts, indicating that no deleterious effects on transcriptional competence, stability of the transcripts, or processing result from insertion of the 21-base-pair lac operator DNA. Incubation of pre-tRNA molecules that contained intervening sequences but were 5' and 3' mature with a yeast ribosomal wash fraction resulted in excision of the intervening sequence and, in the presence of ATP, ligation of the resulting half-tRNA molecules. The presence of RNA complementary to lac operator DNA neither inhibited the excision and splicing activities nor altered the site of the junction.

Abstract
Tetrabutylammonium fluoride will remove phenyl, trichloroethyl and cyanoethyl groups from nucleotides. In addition to the desired nucleotide products other results including chain cleavage, phosphofluoridates and cyanoethylated thymidine units may be obtained depending on the conditions used. Fluoride ion has been used to successfully exchange phenyl and trichloroethyl groups for methyl, ethyl and butyl groups in nucleotide triesters. This represents a rapid high yield route to a variety of phosphate esters. The synthesis of a novel nucleotide analogue in which two chains are bridged through their phosphates is described.

Abstract
Preparative reversed-phase thin layer chromatography on silanized silica-gel (RP-2 and RP-18) has been developed to purify triester deoxyribooligonucleotides prepared by the modified triester method. The effectiveness of this technique has been demonstrated in the rapid synthesis of eight pure deoxyribooligonucleotides constituting the sequence of human insulin A DNA. The sequence of each of the deoxyribooligonucleotides was confirmed by the two-dimensional mobility-shift method of finger-printing.

Abstract
A method for peptide synthesis is proposed based on a template-directed scheme that parallels that of the native ribosomal mechanism. In this procedure, peptide bond formation is facilitated by the juxtaposition of aminoacyl and peptidyl oligonucleotide carriers bound adjacent to one another on an oligonucleotide template. The general strategy of the synthesis and relevant model studies are described. The scheme provides an intrinsic mechanism by which oligonucleotides can direct the synthesis of polypeptides in the absence of protein or ribosomal machinery and, as such, suggests a model for the origin of prebiotic protein synthesis.

Abstract
We report simplified methods for large scale enzymatic synthesis of oligoribonucleotides using polynucleotide phosphorylase. The main features of the method are use of RPC-5 chromatography, including chromatography at two pH values to deal with the problem of primer phosphorolysis, rapid dialysis for large scale desalting, simplified methods for enzyme removal, and high resolution 1H and 31P NMR for product identification and demonstration of purity. The capacity of the method is adequate to allow beginning with grams of material in the first polymerization step, so that product yields of several milligrams, sufficient for many physical studies, are possible after as many as three separate polymerization reactions.

Abstract
The synthesis of the hexanucleotide d)A-C-C-A-G-C), complementary to the 2 major triplets of fibroin mRNA, using the phosphotriester methodology is described. The protected dinucleotides ((MeO)2Tr)dbzA.anC, ((MeO)2Tr)danC.bzA and ((meO)2Tr)dacG.anC were synthesized; the latter two were detritylated and joined in stepwize fashion to the 1st to form the protected hexanucleotide ((MeO)2Tr)dbzA.anC.anC.bzA.acG.anC. The latter was deblocked with NH3 and acid to form the hexanucleotide d(A-C-C-A-G-C). In view of the ability of a prototype affinity column, oligo dC-cellulose, to isolate fibroin mRNA, prospects appear excellent for the d(A-C-C-A-G-C)-cellulose affinity column isolation of fibroin mRNA.

Abstract
The nitrocellulose filter assay was used to study the interactions of wild-type (SQ) and tight-binding (QX86) lac repressors with synthetic lac operators 21 and 26 base pairs long. The repressor binding properties of both operators were very similar, indicating that both contain the same specific repressor recognition sites. The repressor-operator association rate constants (k(a)) were more sensitive than dissociation rate constants (k(d)) to changes in ionic strength. The responses of both k(a) and k(d) to ionic strength were relatively small compared to the effects previously observed with lambdah80dlac as operator DNA. These results suggest that under natural conditions there are electrostatic interactions between lac repressor and DNA regions outside of the 26 base pair operator sequence. Association rate constants for SQ repressor with either operator are higher than have been predicted for diffusion-limited reactions. We postulate that long-range electrostatic attractions between repressor and operator accelerate the association reaction. The presence of nonoperator DNA decreased association rate constants, the effect being more noticeable at an ionic strength of 0.05 M than at 0.20 M. Nonoperator DNA reduced k(a) values for associations involving QX86 repressor to a greater extent than for those with SQ repressor. The two types of repressors also had different rate constants for interactions with synthetic operators. The values for k(a) and k(d) were both higher with SQ repressor than with QX86 repressor. However, the rate constants were more sensitive to ionic strength when the repressor used was QX86.

Abstract
Chemically synthesized lactose operator DNA was tested for binding with lactose repressor protein. These operator DNAs were found to (1) bind specifically to lactose SQ repressor as measured by release of binding with the inducing ligand isopropyl-beta-D-thiogalactoside, (2) have dissociation half-lives of 37 seconds (21 base-paired duplex) and 46 seconds (26 base-paired duplex) and (3) have dissociation half-lives with x86 repressor of 9 minutes (21 base-paired duplex) and 18 minutes (26 base paired duplex). Modified operators containing 5-bromodeoxyuridine and deoxyuridine at specific sites were also prepared. These analogs bound both repressors about as tightly as the wild type sequence.

Abstract
A number of specific duplex DNA sequences which correspond to varying lengths of the lactose operator region have been synthesized by a combination of chemical and enzymatic methods. Repressor binding studies on these synthetic duplex operator molecules show that all the nucleotides essential for full lactose operator-repressor interactions are included in a 17-nucleotide-long duplex DNA that constitutes the minimal recognition sequence for this DNA-protein interaction.
