Unformatted text preview: -Primase help create primers which are needed for DNA Polymerase III to begin its task. It also fills in the gaps of Okazaki fragments with RNA nucleotides. DNA: Deoxyribose. Thymine. Double Stranded. RNA: Ribose. Uracil. Single Stranded. Prokaryotes: one dnaB. Eurkaryotes: many dnaB spots. Eukaryotes have nucleus. 1.dnaB binds to origin. 2. DNA gyrase (2) relaxes and makes a cut in the helicase. 3.Helicase unwinds DNA strands. 4.SSBP keeps the strands apart. 5. Primase help create RNA primer and makes primers between Okazaki fragments. 6. DNA Polymerase III is involved in the polymerization of DNA from 5`to 3`. 7.DNA Polymerase I removes primers and replaces them with DNa nucleotides. 8. DNA Ligase seals adjacent DNA nucleotides by making a phosphodiester bonds between the nucleotide....
