Eukaryotic replication notes
WebDec 24, 2024 · It occurs in three main stages: initiation, elongation, and termination. DNA replication in eukaryotes occurs in three stages: initiation, elongation, and termination, which are aided by several enzymes. Initiation Eukaryotic DNA is bound to proteins known as histones to form structures called nucleosomes. WebReplication in eukaryotes starts at multiple origins of replication. The mechanism is quite similar to prokaryotes. A primer is required to initiate synthesis, which is then extended by DNA polymerase as it adds nucleotides one by one to the growing chain.

The mechanism of eukaryotic DNA replication is similar to that of prokaryotic DNA replication. However, eukaryotic DNA replication requires special consideration due to differences in DNA sizes, unique linear DNA end structures called telomeres, and distinctive DNA packaging that involves complexes with histones.
