-Which scientist discovered the nuclei from WBC contained nucleic acids? MIESCHER -In the experiments of Hershey and Chase: DNA is the genetic material. -The two strands of DNA in the double helix are held together: by hydrogen bonds between the bases. -Chargaff is credited for stating that one purine for a base pair with one pymidine. -DNA Polymerase III does all of the following except add nucleotides to a phosphate group. Watson and Crick are credited for predicting that DNA self-replicates. -A nucleotide could be DNA or RNA. It contains a sugar, nitrogen, and phosphate group. Contains genetic information. -Okazaki Fragments are short segments of DNA on the lagging strand, it’s built discontinuously away from the replication fork. -Phosphodiester bonds bond the sugar to the phosphate group in DNA and RNA.

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....
