In what stage is dna replicated
Web4 apr. 2024 · INTRODUCTION. Mitochondria and their 16.5-kb circular genomes (mtDNA) undergo constant turnover in arrested primary oocytes for decades in humans (1, 2).Frequent DNA replication and lack of efficient DNA repair mechanism in the mitochondrion contribute to a mutation rate that is ∼10-fold higher than that of the … Web21 feb. 2024 · The mechanism by which polymerase α - primase (polα-primase) synthesizes chimeric RNA-DNA primers of defined length and composition, necessary for replication fidelity and genome stability, is unknown. Here, we report cryo-EM structures of polα-primase in complex with primed templates representing various stages of DNA synthesis.
