  1. 1. Meiotic chromosome segregation : molecular analysis of the synaptonemal complex

    Författare :Li Yuan; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Meiosis is a special type of cell division that produces haploid gametes from diploid parental cells. As such, meiosis stands at the gateway to sexual reproduction in most eukaryotic organisms. During meiosis, a complex, but tightly coordinated series of events occur. Homologous chromosomes come together and pair along their entire length. LÄS MER

  3. 2. Structural maintenance of chromsomes : a complex tale of genomic integrity

    Författare :Hanna Betts Lindroos; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Genomic integrity is an absolute requirement for cell survival. Programmed events such as genome rearrangements and DNA replication can cause lesions in the DNA, as can exogenous agents such as radiation and chemicals. One of the most austere types of lesion is DNA double strand breaks (DBSs). LÄS MER

  4. 3. Maintenance of genome integrity via activities of the cohesin network

    Författare :Emma Lindgren; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Correct segregation of sister chromatids is an important mechanism for keeping the genome intact. The cohesin complex holds the sister chromatids together from the time of their formation during replication, until separation at anaphase and is thereby mediating cohesion between the sister chromatids, essential for correct chromatid segregation.

  5. 4. The Smc5/6 complex : the mysterious guardian of genome stability

    Författare :Davide G Berta; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : An intricate network of proteins ensures the faithful transmission of genetic information through cell generations. The Structural Maintenance of Chromosomes (SMC) protein complex family plays a pivotal role in maintaining genome stability. LÄS MER

  7. 5. The Smc5/6 complex : linking DNA replication with chromosome segregation

    Författare :Kristian Jeppsson; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : In order to faithfully propagate the genetic material from one generation to the next, cells need to properly replicate and segregate their chromosomes. The three well-conserved eukaryotic Structural Maintenance of Chromosomes (SMC) protein complexes, cohesin, condensin and the Smc5/6 complex (Smc5/6) organize chromosomes to ensure that the daughter cells receive a full complement of chromosomes.
