Abstract Transcription factors (TFs) play an essential role in molecular biology by regulating gene expression. The binding sites of TFs can vary a large amount and the numerous possible locations make their detection challenging issue. Recently, several machine learning approaches using nucleotide sequence data were applied to classify DNA sequences regarding Factor Binding Sites (TFBS). We pr...

In spite of the important role played by DNA sequences in living matter, it is only relatively recently that general methods for their determination have been developed. This is mainly because of the very large size of DNA molecules, the smallest being those of the simple bacteriophages such as qXl74 (which contains about 5,000 nucleotides). It was therefore difficult to develop methods with su...

Globin messenger RNA, isolated from human peripheral blood reticulocytes, was transcribed into complementary DNA by use of the RNA-dependent DNA polymerase of avian myeloblastosis virus. The complementary DNA was then transcribed into (32)P-labeled complementary RNA by E. coli RNA polymerase in the presence of alpha-(32)P-labeled ribonucleoside triphosphates. The fingerprint pattern obtained fr...

This paper explores the connection between the size of the spectral coefficients of a nucleotide or any other symbolic sequence and the distribution of nucleotides along certain subsequences. It explains the connection between the nucleotide distribution and the size of the spectral coefficients, and gives a necessary and sufficient condition for a coefficient to have a prescribed magnitude.
