In the hypotrichous ciliated protozoan Oxytricha nova, approximately 95% of the micronuclear genome, including all of the repetitive DNA and most of the unique sequence DNA, is eliminated during the formation of the macronuclear genome. We have examined the interspersion patterns of repetitive and unique and eliminated and retained sequences in the micronuclear genome by characterizing randomly...

Integration of transgenic DNA into the plant genome was investigated in 13 transgenic oat (Avena sativa L.) lines produced using microprojectile bombardment with one or two cotransformed plasmids. In all transformation events, the transgenic DNA integrated into the plant genome consisted of intact transgene copies that were accompanied by multiple, rearranged, and/or truncated transgene fragmen...

Genome sizes and the organization of repetitive DNA were determined in the hard ticks Ixodes scapularis and Boophilus microplus using reassociation kinetics. The I. scapularis genome contains approximately 2.15 pg (2.1x10(3) Mbp) of DNA and consists of no foldback (FB), 27% highly repetitive (HR), 39% moderately repetitive (MR), and 34% unique DNA. The B. microplus genome contains 7.5 pg (7.1x1...

Human telomeres are composed of tandem arrays of TTAGGG repeats with many variant repeats at the proximal ends. Comparison of the interspersion of variant and TTAGGG repeats between alleles can be used to study telomere instability, but the difficulty in identifying chromosome-specific sequences close to the start of autosomal telomeres has hampered such investigations. A chromosome end, includ...

This study generates data concerning the genome of a flightless species of bird, the emu. We examined and ultimately rejected the following hypotheses: (1) Microsatellites are randomly distributed throughout the emu genome. (2) The relative order of abundance of dinucleotides will be constant across genomes. (3) Interspersion distances for a given dinucleotide will be equal across vertebrate ge...

Lambda words are sequences obtained by encoding the differences between ordered elements of the form i + jθ, where i and j are non-negative integers and 1 < θ < 2. Lambda words are right-infinite words defined over an infinite alphabet that have connections with Sturmian words, Christoffel words, and interspersion arrays. We show that Lambda words are infinite rich words. Furthermore, any Lambd...

The peptide PcL342-354C was obtained from the Cry1Ab16 toxin present in Bacillus thuringiensis ("Computational Modeling Deduced Three Dimensional Structure of Cry1Ab16 Toxin from B. thuringiensis AC11" (Kashyap, 2012) [1]). In this data article, we report the synthesis and characterization of the PcL342-354C peptide by MALDI-TOF/TOF mass spectrometry. In addition, the preparation of layer-by-la...
