• Sao chép fork – the junction between the newly separated
template strands and the unreplicated duplex DNA
• Leading strand – DNA strand synthesized continuously
• Lagging strand - DNA strand synthesized discontinuously
• Okazaki fragments – short fragments of new DNA formed on the lagging strand – 1,000-2,000 nucleotides in bacteria and 100-400 nucleotides in eukaryotes
• The looping of the template for the lagging strand allow the replication fork to move to one direction
