  2. 1. Using Trees to Capture Reticulate Evolution : Lateral Gene Transfers and Cancer Progression

    Author : Ali Tofigh; Jens Lagergren; Mike Steel; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Lateral Gene Tranfer; Horizontal Gene Transfer; Cancer Progression; Bioinformatics; Bioinformatik; Computer science; Datalogi;

    Abstract : The historic relationship of species and genes are traditionally depicted using trees. However, not all evolutionary histories are adequately captured by bifurcating processes and an increasing amount of research is devoted towards using networks or network-like structures to capture evolutionary history.

  4. 2. Methods and applications in DNA sequence alignments

    Author : Ellen Sherwood; Karolinska Institutet; Karolinska Institutet; []
    Keywords : DNA sequence alignment; CNV; Chicken; Trypanosoma cruzi.;

    Abstract : DNA sequence alignment is one of the most common bioinformatics tasks. Alignment analysis for eukaryotic genomes is challenging because the datasets are large. Repeat sequences also make the analysis difficult. This thesis describes new methods which we have developed for DNA sequence alignment that address these problems. READ MORE

  5. 3. Retroviral long Terminal Repeats; Structure, Detection and Phylogeny

    Author : Farid Benachenhou; Jonas Blomberg; Göran Sperber; Aris Katzourakis; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Retrovirus; long terminal repeats; hidden Markov models; phylogeny; alignment; conserved motif; stem-loop; Clinical virology; Klinisk virologi; Klinisk virologi; Clinical Virology;

    Abstract : Long terminal repeats (LTRs) are non-coding repeats flanking the protein-coding genes of LTR retrotransposons. The variability of LTRs poses a challenge in studying them. Hidden Markov models (HMMs), probabilistic models widely used in pattern recognition, are useful in dealing with this variability. READ MORE

  6. 4. Enabling massive genomic and transcriptomic analysis

    Author : Henrik Stranneheim; Joakim Lundeberg; Elaine Mardis; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; DNA; RNA; sequencing; massively parallel sequencing; alignment; assembly; single nucleotide polymorphism; LHON;

    Abstract : In recent years there have been tremendous advances in our ability to rapidly and cost-effectively sequence DNA. This has revolutionized the fields of genetics and biology, leading to a deeper understanding of the molecular events in life processes. READ MORE

  7. 5. Identification and characterisation of the novel mammalian gene family Elovl

    Author : Abolfazl Asadi; Leif Andersson; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; zoofysiologi; Zoological physiology;

    Abstract : Comparative analysis is one of the foremost tools in biology. The most common comparative method is sequence alignment, which can be performed in many ways. By using any sort of alignments, competing sequences are evaluated by scoring schemes for estimating similarity. READ MORE
