Circular splicing has been very recently introduced to model a specific recombinant behaviour of circular DNA, carrying on the investigation initiated with linear splicing. In this paper we restrict ourselves to the relationship between circular regular languages and circular splicing languages.

Conformation and circular dichroism of DNA
Biopolymers, 1979AbstractCD spectra of calf thymus, C. perfringens, E. coli, and M. luteus DNA have been measured in the vacuum‐uv region to about 168 nm for the A‐, B‐, and C‐forms. The positive band at about 187 nm and the negative band at about 170 nm found for each type and form of DNA are sensitive to the source of the DNA and the base–base interactions of the ...

Modifications of Circular DNA by Photoalkylation
Radiation Research, 1985The effects of photoalkylation on superhelical PM2 DNA were examined. The chief product was 8-(2-hydroxy-2-propyl)guanine, formed exclusively in sequences of alternating purines and pyrimidines. Other purine damages included 8-(2-hydroxy-2-propyl)adenine and smaller quantities of two uncharacterized adenine products.

Circular, repetitive DNA in yeast
Biochimica et Biophysica Acta (BBA) - Nucleic Acids and Protein Synthesis, 1972Abstract The fraction of repetitive DNA and the small circular DNA with nuclear density from Saccharomyces cerevisiae are shown to be identical.

Circular dichroism of superhelical DNA
Biopolymers, 1971AbstractThe circular dichroism (CD) spectra of a number of superhelical DNA's have been measured. The introduction of negative superhelical turns causes an increase in magnitude of the positive band around 280 mμ, while the trough around 250mμ is little affected.

Circular DNA and splicing systems
1992Circular strings representing DNA molecules and certain recombinant behaviour are formalized. Various actions of splicing schemes on linear and circular DNA molecules are examined. It is shown that there is a difference in the regularity result of Culik and Harju [1] between the linear and circular strings.

Summary Closed duplex (cd) and open circular (oc) forms of DNA of the plasmid Col E1 were studied by means of a.c. and differential pulse polarography (d.p.p.). Adsorption properties of oc DNA (at pH 8) agreed in principle with those of linear DNAs. cd DNA was less firmly adsorbed at the d.m.e. compared with oc DNA.

In this chapter the statistical-mechanical and transport theories of the HW chain developed so far are applied to some interesting problems of circular DNA such as cyclization of linear DNA and analysis of circular DNA topoisomers (topological isomers) or supercoiled forms.
