  7. 5. Regulation of G2 phase and long-term consequences of DNA damage

    Författare :Anna Won Middleton; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Cell proliferation requires the accurate replication of DNA and equal segregation of replicated genes, important for maintaining the integrity of newly formed cells. At the centre of this process is a series of coordinated events termed ‘the cell cycle’, which ensures cell proliferation proceeds with high fidelity. LÄS MER
