Database searching with DNA and protein sequences: An introduction [PDF]
This review of sequence database searching aims to set out current practice in the area, in order to give practical guidelines to the experimental biologist. It describes the basic principles behind the programs and enumerates the range of databases available in the public domain.

Comparative statistics for DNA and protein sequences: single sequence analysis. [PDF]
Four categories of data representations are used to help interpret structures and similarities of nucleic acid and protein sequences. Statistical significance of the observed relationships revealed by these representations are assessed by a hierarchy of permutation procedures and by comparisons with theoretical random models. Applications are presented

Comparative statistics for DNA and protein sequences: multiple sequence analysis. [PDF]
Concepts and methods [Karlin, S. & Ghandour, G. (1985) Proc. Natl. Acad. Sci. USA 82, 5800-5804] for the analysis of patterns and relationships are extended to multiple DNA and protein sequences. Functionals include multiple sequence common word occurrence distributions, characterizations of high frequency shared words, and ascertainment of long ...

PATTERNFINDER: combined analysis of DNA regulatory sequences and double-helix stability
Background Regulatory regions that function in DNA replication and gene transcription contain specific sequences that bind proteins as well as less-specific sequences in which the double helix is often easy to unwind.

Sequence specific interaction of the chromosomal proteins with DNA [PDF]
Calf thymus chromatin was partially deproteinized by 0.6-1 M NaCl extraction. From the shape of the temperature derivative plot of its melting curve, the DNA in each chromatin was resolved into regions of exposed DNA, and DNA still complexed with proteins.

Improved Algorithm for Analysis of DNA Sequences Using Multiresolution Transformation
Bioinformatics and genomic signal processing use computational techniques to solve various biological problems. They aim to study the information allied with genetic materials such as the deoxyribonucleic acid (DNA), the ribonucleic acid (RNA), and the ...

H-NS can facilitate specific DNA-binding by RNA polymerase in AT-rich gene regulatory regions.
Extremely AT-rich DNA sequences present a challenging template for specific recognition by RNA polymerase. In bacteria, this is because the promoter -10 hexamer, the major DNA element recognised by RNA polymerase, is itself AT-rich.
