Current Opinion in Chemical Biology, 1999
Last year provided new structural data, particularly for the group I intron and the Hepatitis delta ribozymes, that were essential for a better understanding of the RNA structure/function relationship. The role of metal ions in catalysis of ribozyme action still remains elusive, however.

Current Opinion in Biotechnology, 2005
Since the discovery of the first natural ribozyme more than 20 years ago, it has become clear that nucleic acids are not only the static depository of genetic information, but also possess intriguing catalytic activity. The number of reactions catalyzed by engineered nucleic acid enzymes is growing continuously.

Nucleic acids and polynucleotides
Journal of Cellular Physiology, 1969The conformation of native double helical DNA is well-known, but it is possible that small regions occur within native DNA, undetectable by X-ray diffraction methods, which have different conformations. Model structures are the synthetic deoxypolynucleotides of defined sequence. Under the conditions used, DNA, poly d(A-T) • poly d(A-T), and poly d(T-G)

Current Protocols in Cytometry, 2003
AbstractThis unit describes the physicochemical structures of commonly used nucleic acid probes, classified into four groups based on their mode of nucleic acid binding. The unit provides an excellent background for the many protocols employing these dyes and should be a prerequisite for any studies involving nuclear probes.

I N 1953 Watson and Crick [I] proposed a model for the structure and replication of DNA and in doing so inaugurated the science known as molecular biology. In the intervening ten years, advance in this subject has been spectacular. It can now be seen that the general principles which govern the controlled functioning and self-replication of living ...

Summary Present knowledge about the structure and function of mtDNA and its transcription products is briefly discussed with special emphasis on the unusual structure of mtDNA in Tetrahymena pyriformis and recent experiments on the possible import of mRNA into mitochondria.

Publisher Summary The history of the study of the nucleic acids has in fact been a tragic-comedy of the application of drastic methods to materials that in many ways are less stable than most proteins and are also susceptible to attack by a large number of enzymes, many of which are extremely stable and most of which are widely distributed.

Abstract It may be of some advantage to review, within the context of the problem of programing of information in the cell, some of the concepts which have been elaborated. An outline of the basic mechanisms of information transfer was indicated in the first section.
