How do eukaryotes initiate replication
WebMany eukaryotes also reproduce sexually, where a process called meiosis reduces the number of chromosome by half to produce haploid cells (typically called sperm or eggs), and then two haploid cells fuse to create a new organism. Archaea and bacteria cannot reproduce sexually. WebIn eukaryotes, the low-processivity enzyme, Pol α, helps to initiate replication because it forms a complex with primase. [28] In eukaryotes, leading strand synthesis is thought to be conducted by Pol ε; however, this view has recently been challenged, suggesting a …
