Figure 1 illustrates the differences between the three proposed mechanisms of DNA replication. The leading and lagging strands are synthesized in the similar fashion as in prokaryotic DNA replication. The codon it belongs to may actually code for the same amino acid (see the chart above to see how this could happen). Each molecule consists of a strand from the original molecule and a newly formed strand. DNA replication is the process in which DNA is copied. The mechanism of DNA replication in eukaryotes is similar to DNA replication in prokaryotic.

Paperclip DNA Replication DNA Replication Overview: • To “replicate” DNA means to produce an exact copy of itself. DNA replication in eukaryotes is different than bacterial replication by primase consisting of DNA polymerase and two smaller proteins create RNA primer and initiator DNA, and two different DNA polymerases synthesize the lagging and leading strands. DNA Pol I has a 5′ to 3′ exonuclease activity in addition to its polymerase activity, and uses its exonuclease activity to degrade the RNA primers ahead of it as it extends the DNA strand behind it, in a process called nick translation.
