• Based on these evolutionary transformations, a computing model has been formulated in formal language theory known as insertion-deletion systems. (inria.fr)
  • Recently, in , a new computing model named Matrix insertion-deletion system has been introduced to model various bio-molecular structures such as hairpin, stem and loop, pseudoknot, attenuator, cloverleaf, dumbbell that occur at intramolecular level. (inria.fr)
  • In this paper, we model some of the intermolecular structures such as double strand languages, nick languages, hybrid molecules (with R-loops), holliday structure, replication fork and linear hybridization (ligated) languages using Matrix insertion-deletion system. (inria.fr)
  • Low-complexity regions are regions in the sequence with only a few amino acids, which in turn, causes redundancy within that small or limited region. (wikipedia.org)
  • Therefore, the sequence of the mature ActA protein consist of 610 amino acids. (wikipedia.org)
  • The sequences of amino acids in polypeptide chains that form proteins determine the proteins' structure and function. (wikipedia.org)
  • It was for some years unclear if the function of Spot 42 was mediated through the 109 nucleotide RNA itself or if the function was mediated through the 14 amino acids long peptide which is hypothetically encoded from within the sRNA sequence. (wikipedia.org)
  • This was based on the observation that Spot42 contains structural features similar to other non-coding RNAs found in E. coli (such as 6S RNA and lambda bacteriophage), as well as features that are typically found in mRNAs (i.e., polypurine sequence followed by AUG, 14 amino acids and an UGA terminator).

  • This deletion region overlaps the BRCA1 locus, which predisposes to familial breast and ovarian cancer. (aacrjournals.org)
  • We have analyzed patients with isolated lissencephaly sequence (ILS) by FISH with probes at D17S379, an anonymous locus distal to LIS1, and with LIS1 specific probes. (ovid.com)
  • The methodology is based on the preselection of target DNA by excluding redundant sequence within the NF2 locus using bioinformatics. (cf.ac.uk)
  • allele one of multiple alternative forms of a single gene, each of which is a viable DNA sequence occupying a given position, or locus on a chromosome. (wikipedia.org)
  • by fusion of mouse constructs fused to basal promoter with LacZ expression for hCONDELs near the androgen receptor (AR) locus and the growth arrest and DNA-damage-inducible protein GADD45 gamma (GADD45G) locus suggest a role in deletions that affect regulatory sequences in humans. (wikipedia.org)
  • citation needed] The 60.7kb hCONDEL which is located near the AR locus has been found to be responsible for removing a 5 kb sequence that codes for an enhancer for the AR locus. (wikipedia.org)
  • In this study we apply a PCR-based, strictly sequence-defined, repeat-free approach for the preparation of a diagnostic microarray for the detection of disease-causing deletions in the NF2 gene. (cf.ac.uk)
  • Expression data from Expressed Sequence Tag mapping, microarray and in situ hybridization show high expression for Homo sapiens in the blood, bone marrow and nerves. (wikipedia.org)
  • In addition, 436 chromosome deletion lines are available for the 21 wheat chromosomes that can be used for intrachromosomal mapping ( E ndo and G ill 1996 ). (genetics.org)
  • Phylogenetic comparison of telomerase RNA sequences from several budding yeasts revealed a core structure common to Saccharomyces and Kluyveromyces yeast species. (isharonline.org)
  • By determining the presence or absence of CSIs in an out-group species, one can infer whether the ancestral form of the CSI was an insert or deletion and this can be used to develop a rooted phylogenetic relationship among organisms. (wikipedia.org)
  • Phylogenetic footprinting is a technique used to identify transcription factor binding sites (TFBS) within a non-coding region of DNA of interest by comparing it to the orthologous sequence in different species. (wikipedia.org)
  • Unlike DNase footprinting, phylogenetic footprinting relies on evolutionary constraints within the genome, with the "important" parts of the sequence being conserved among the different species. (wikipedia.org)
  • Similarly, the sequence धड़कने in दिल धड़कने लगा (the heart started beating) and in दिल की धड़कनें (beats of the heart) is identical prior to the nasalisation in the second usage. (wikipedia.org)
  • After aligning the two sequences, the percentage of identical base pairs is computed. (wikipedia.org)
  • Archaea), it can be inferred whether the indel is an insert or a deletion, and which of these two groups A, B, C or X, Y, Z is ancestral. (wikipedia.org)
