Homework Answers
Answer:
Primase : Synthesizes short sequence of RNA required for DNA replication
Helicase: Break hydrogen bonds, unwinding DNA
Single-stranded binding protein: Coats DNA, preventing duplex formation
DNA polymerase III: Starts DNA synthesis at the 3' end of primer
DNA polymerase I: Removes RNA primers and replaces them with DNA nucleotides
DNA ligase: Catalyzes the formation of phosphodiester bond between DNA fragments.
Topoisomerase: Unwinds supercoiled DNA by catalyzing the uncontrolled cleavage and rejoining of DNA
