Match the enzyme to the function it nerforms in re-Iication. — II [ Choose ] Can create a double-strand break on DNA to relieve overwinding that occurs behind replication forks DNA helicases Coat the DNA template to keep it straight and prevent hairpin formation Open up the double-helix to create single-stranded DNA in front of the replication fork Synthesize DNA by adding nucleotides to the 5‘ end of the growing strand DNA primase \/ An RNA polymerase that creates short stretches of RNA that serve as starting points for DNA synthesis Creates a break (“nick“) on one strand of DNA to relieve overwinding that occurs in front of replication forks Coats RNA primers to stabilize them and ensure they are permanently part of the replicated DNA Single»strand DNA-binding protei Synthesize DNA by adding nucleotides to the 3' end of the growing strand Joins the 3' end of one stretch of newly synthesized DNA to the 5' end of the adjacent stretch of newly synthesized DNA DNA ligase Ligates each new nucleotide to the complimentary nucleotide on the template strand A large complex that binds to the origin of replication in eukaryotes Adds a sliding clamp to sites where DNA polymerization will begin Sliding clamp Forms a ring around the DNA to keep the DNA polymerase from falling off before it reaches the end of the single-stranded template Creates DNA primers to have a place to initiate elongation reactions for DNA replication DNA topoisomerase I Can create a double-strani v You to Everyone SN In the image depicted above B v considered as the lagging strant because leading strand opens ir direction from 5‘ to 3‘ in the replication fork and therefore lag creates DNA Primers '0 h‘ V strand in the above picture will l as the strand opens in the 3‘ to direction towards the replicatior A large complex that binds V This mechanism is necessary be .c ."t at.“ nut L.-u.. ..
