  1. 1. Vinst och förlust : en fylogenetisk studie av kloroperoxidas-liknande enzym hos jästsvampar

    Kandidat-uppsats, SLU/Department of Molecular Sciences

    Författare :Beatrice Bylén; [2021]
    Nyckelord :fylogenetik; sekvenshomologi; Saccharomycotina; knoppjästsvamp; HGT; genförlust; α β-hydrolas; kloroperoxidas;

    Sammanfattning : Knoppjästsvampar är en typ av svampar med encellig morfologi. Knoppjästsvampar utgör Saccharomycotina, en understam till Ascomycota och innefattar mer än 1000 idag beskrivna arter, bland annat bakjästen Saccharomyces cerevisiae. Trots att S. LÄS MER

  3. 2. The transfer of chromosomal genes through bacterial conjugation in Escherichia coli

    Master-uppsats, Uppsala universitet/Institutionen för medicinsk biokemi och mikrobiologi

    Författare :Arijana Katana; [2021]
    Nyckelord :conjugation; escherichia coli; hybrid;

    Sammanfattning : Evolution in bacteria occurs through the combined effects of spontaneous mutations and horizontal gene transfer (HGT). Several mechanisms can lead to HGT: (i) transformation, the uptake of DNA from the environment; (ii) transduction, the transfer of DNA carried by a bacteriophage into another bacterium during infection; and (iii) conjugation, bacterial mating mediated by a conjugative plasmid like the F-factor.

  4. 3. The Importance of Bacterial Replichore Balance

    Master-uppsats, Uppsala universitet/Institutionen för medicinsk biokemi och mikrobiologi

    Författare :Ender Efe Cerit; [2021]
    Nyckelord :Salmonella; bacterial evolution; fitness cost; chromosome organization and structure; chromosomal inversion; replichore; horizontal gene transfer;

    Sammanfattning : In most bacterial pathogens, the genome is comprised within a single circular chromosome which is typically organized by the origin-to-terminus axis that divides the chromosome into equally-sized arms of replication (replichores). This similarity in length is presumed to be required for the synchronization of the two replication forks to meet at the terminus for efficient chromosome segregation. LÄS MER

  5. 4. Language IndependentDetector for Auto GeneratedTweets

    Master-uppsats, Linnéuniversitetet/Institutionen för datavetenskap (DV)

    Författare :Saeideh Valipour; [2020]
    Nyckelord :Twitter; Machine Learning; Classification; Bot Detection; Social networks;

    Sammanfattning : The cross-disciplinary Nordic Tweet Stream (NTS) is a project aiming at creating a multilingual text corpus consisting of tweets published in the five Nordic countries. The NTS linguists are explicitly interested in tweets having a text formulated by a human where each tweet is a personal statement, not in Tweets generated by bots and other programs or apps since they might skew the results.

  7. 5. Whole genome assembly, annotation and bioinformatics analysis of streptococcus agalactiae isolated from cow suffering of mastitis

    Master-uppsats, SLU/Dept. of Animal Breeding and Genetics

    Författare :Saima Zubair; [2010]
    Nyckelord :Streptococcus agalactiae; Next Generation Sequencing Technologies; Reference-guided Assembly; Mastitis; Horizontal Gene Transfer; Secretory Proteins;

    Sammanfattning : Streptococcus agalactiae is an obligate parasite and contagious pathogen living within the epithelial cells lining of acini of the bovine udder, causing milk disease mastitis particularly subclinical mastitis in dairy cattle. This bacterial pathogen also causes infection in pre-milking heifers, as well as neonates. LÄS MER
