Decoding sequences that stem from multiple transmissions of a codeword over an insertion, deletion, and substitution channel is critical component efficient deoxyribonucleic acid (DNA) data storage systems. In this paper, we consider concatenated coding scheme with outer nonbinary low-density parity-check code or polar either inner convolutional time-varying block code. We propose two novel dec...

Ochrobactrum intermedium is an opportunistic human pathogen belonging to the alpha 2 subgroup of proteobacteria. The 16S rDNA sequences of nine O. intermedium isolates from a collection of clinical and environmental isolates exhibited a 46-bp insertion at position 187, which was present in only one sequence among the 82 complete or partial 16S rDNA sequences of Ochrobactrum spp. available in da...

In this paper, we propose and investigate the use of a modifiedversion Intermediate Significant Bit (ISB) insertion algorithm, so-called here as MISB algorithm for secret text steganography. The is passed through sequence ciphering techniques. A Modified proposed hiding bit sequences cipher into time-frequency domain using wavelet transform image pixels, in order to improve robustness Steganogr...

Two macromolecular sequences which have evolved from a common ancestor sequence will tend to include a large number of elements unaffected by replacement mutations in both sequences, as long as the evolutionary rate is not too high or the divergence time is not too great. The positions of corresponding elements may have changed in either daughter sequence due to deletion/insertion mutations inv...

Background Genetically modified organisms (GMOs) have numerous biomedical, agricultural and environmental applications. Development of accurate methods for the detection of GMOs is a prerequisite for the identification and control of authorized and unauthorized release of these engineered organisms into the environment and into the food chain. Current detection methods are unable to detect unch...

Rhizobia are a group of bacteria that form nodules on the roots of legume host plants. The sequenced genomes of the rhizobia are characterized by the presence of many putative insertion sequences (IS) elements. However, it is unknown whether these IS elements are functional and it is therefore relevant to assess their transposition activity. In this work, several functional insertion sequences ...

Two new insertion sequences, ISCce1 and ISCce2, were found to be inserted into the cipC gene of spontaneous mutants of Clostridium cellulolyticum. In these insertional mutants, the cipC gene was disrupted either by ISCce1 alone or by both ISCce1 and ISCce2. ISCce1 is 1,292 bp long and has one open reading frame. The open reading frame encodes a putative 348-amino-acid protein with significant l...

The nucleotide sequences at the ends of the Tn4 transposon (mercury spectinomycin and sulfonamide resistance) have been determined. They are inverted repeated sequences of 38 nucleotides with three mismatched base pairs. These sequences are strongly homologous with the terminal sequences of Tn501 (mercury resistance) but less so with those of Tn3 (ampicillin resistance). The Tn4 transposon gene...
