MOLECULAR STRUCTURE OF DEOXYRIBONUCLEIC ACID (DNA)

Molecular Structure of Deoxyribonucleic Acid (dna)

Although DNA is associated with complex biological phenomena and has many physicochemical properties not easily explained, there is no doubt that the molecule consists to a large extent of the regular, and in some ways simple structure (1-3), derived from x-ray diffraction. We will describe here briefly new data on the s t ruc turethe x-ray diffraction measurements and molecular model building ...

The complementary structure of deoxyribonucleic acid

This paper describes a possible structure for the pamcrystalline form of the sodium salt of deoxyribonucleic acid. The structure consists of two DNA chains wound helically round a common axis, and held together by hydrogen bonds between specific pairs of bases. The assumptions made in deriving the structure are described, and co-ordinates are given for the principal atoms. The structure of the ...

Deoxyribonucleic acid-deoxyribonucleic acid hybridization assay for replication origin deoxyribonucleic acid of Escherichia coli.

Deoxyribonucleic acid (DNA)-DNA hybridization on nitrocellulose filters can be used to assay for replication origin DNA from Escherichia coli if the DNA attached to the filters is enriched for the replication origin sequences. Such DNA can be readily isolated from very rapidly growing cells. When low amounts of this DNA were attached to filters, radioactively labeled DNA from the replication or...
