Occurrence of palindromic sequences in wheat DNA

Plant Science Letters, 1975
Abstract The study of the instantaneously renaturing fraction of wheat DNA provides some evidence for the occurrence of palindromic sequences: after thermal or alkaline denaturation, this fraction elutes from hydroxyapatite as containing double-stranded structures, instantaneously reforming by monomolecular reaction that is characteristic of the ...

The role of palindromic and non-palindromic sequences in arresting DNA synthesis in vitro and in Vivo

Journal of Molecular Biology, 1984
The nature of specific DNA sequences that arrest synthesis by mammalian DNA polymerase alpha in vitro was analyzed using circular, single-stranded M13 or phi X174 virion DNA templates annealed to a unique, terminally labeled, DNA primer. This method rigorously defined both the starting nucleotide position and the direction of synthesis, as well as ...

On the symmetries of multi-palindromic DNA sequences

Journal of Theoretical Biology, 1978
Abstract There are several instances of multiple, overlapping palindromes in DNA sequences which have recently been reported. To ascertain the likelihood of specific biological function for these interdigitating symmetries it is necessary to calculate their probabilities of occurrence.

Cloning and Characterization of DNAs with Palindromic Sequences

1996
A sentence contains an ordered set of letters that is interpreted by reading in one direction, but a palindromic sentence such as “Madam I’m Adam” can be read in either direction. Palindromic sentences are relatively rare because languages use a large number of letters and we normally write sense.

Quasi-palindrome effects on DNA sequence evolution

2017 IEEE International Conference on Bioinformatics and Biomedicine (BIBM), 2017
Quasi-palindromes can be harmful or helpful, but most of this functionality is attributed to the formation of cruciforms. Unfortunately, the general properties a sequence must have to facilitate cruciform formation are poorly understood, as most research has focused on case studies of the unusual secondary structures of a few specific sequences.

The Maximum Length of a Palindrome in a Sequence

1990
The following development of a program to compute the maximum length of a palindrome in a sequence is a tribute to the structured development of programs of which Edsger W. Dijkstra has been such a strong advocate. It shows that our skills have improved over the years, and that we are able to tackle quite non-trivial problems.

Efficient Computation of Palindromes in Sequences with Uncertainties

2017
In this work, we consider a special type of uncertain sequence called weighted string. In a weighted string every position contains a subset of the alphabet and every letter of the alphabet is associated with a probability of occurrence such that the sum of probabilities at each position equals 1. Usually a cumulative weight threshold Open image in new

Notice of Retraction Research on the Palindromic sequences among tRNA sequences

2011 Seventh International Conference on Natural Computation, 2011
Based on all the tRNA sequences with high similarity in their functions and structures, 3420 tRNA sequences are put as a whole in this paper, and then the palindromic sequences of different length within all the tRNA sequences are counted. We observed that: (I) the probability of one given palindromic sequence P(i) with the given palindromic sequence i

Characterization and analysis of biphalin: an opioid peptide with a palindromic sequence

The Journal of Peptide Research, 2001
Abstract:Among the many opioid peptides developed to date as nonaddictive analgesics, biphalin has exhibited extraordinary high potency and many other desirable characteristics. Biphalin is an octapeptide consisting of two monomers of a modified enkephalin, attached via a hydrazine bridge, and with the amino acids assembled in a palindromic sequence ...

In vivo loss of supercoiled DNA carrying a palindromic sequence

Molecular and General Genetics MGG, 1986
Interest in the fate of long palindromic DNA sequences in E. coli has been kindled by the observation that their inviability is overcome in recBC sbcB strains and that these hosts permit the construction of DNA libraries containing long palindromic sequences present in the human genome.
