5 Matching questions

  1. Meselson and Stahl
  2. DNA
  3. Semiconservative Model of DNA Replication
  4. Beadle "Beets" and Tatum
  5. Deoxyribose
  1. a when a double helix replicates, each of the two daughter molecules will have one old strand, derived from the parent molecule and one newly made strand.
  2. b DNA "double helix"
  3. c is antiparallel with a 5'prime end and a 3'prime end
  4. d Neurospora research, experiment on fungus and mold - "one gene one enzyme"
  5. e Models of Replication; Conservative, semiconservative, disruptive/dispersive

5 Multiple choice questions

  1. the rough strand
  2. a structure has two branching "prongs", each one made up of a single strand of DNA. These two strands serve as the template for the leading and lagging strands which will be created as DNA polymerase matches complementary nucleotides to the templates.
  3. untwists the double helix at the replication forks
  4. "T", Thymine
  5. bead-like structures with 140 base pairs of DNA wrapped around a disc of eight histone proteins.

5 True/False questions

  1. P Regionis the small region of a chromosome "petite"

          

  2. Transformationis the large region of a chromosome

          

  3. DNA Polymeraseinstalls new nucleotids; catalyzes the snythesis of new DNA by adding nucleotides to a pre-existing chain.

          

  4. Topoisomeraseand enzyme that adds segments to ends of molecules of DNA/seals the ends acts like bumpers.

          

  5. In what phase does DNA replication take place?when a double helix replicates, each of the two daughter molecules will have one old strand, derived from the parent molecule and one newly made strand.
