WebIn most prokaryotic cells, replication starts from a single point, and it continues in two directions until the whole chromosome is copied. In eukaryotic cells, replication may begin in hundreds of places on the DNA molecule. Replication then occurs in both direction until each chromosome is completely copied. WebFollowing initiation of replication, in a process similar to that found in prokaryotes, elongation is facilitated by eukaryotic DNA polymerases. The leading strand is continuously synthesized by the eukaryotic polymerase enzyme pol δ, while the lagging strand is synthesized by pol ε.
