Matching Pairs DNA Replication Matching GameOnline version Test your knowledge of DNA replication with this fun matching pairs game! by Faith Kollie 1 Replication fork 2 Gyrase 3 DNA replication 4 Okazaki fragments 5 Leading strand (5'-3') 6 Origin of Replication 7 DNA Polymerase 8 Telomerase 9 Ligase 10 Nuclease 11 Primase 12 Lagging strand (3'-5') 13 Helicase Wind DNA helix back up . The area where the replication of DNA will be taking place Used by RNA to add primer . The fragments that grow on the lagging strand in a 5' to 3' .direction Adds nucleotide to new strand; proofreads as nucleotides are added; removes error and adds correct nucleotide . Untwists double helix at replication fork separating them . Cuts out damaged DNA segments . Lengthens telomeres; protects the ends of DNA . Joins sugar and phosphates of Okazaki fragments; acts as a glue . Site where replication begins; specific nucleotide sequence . One strand being replicated into two identical strands . Replicates away from replication fork in fragments . Replication toward replication fork .
