- Meselson and Stahl
- Semiconservative Model of DNA Replication
- Beadle "Beets" and Tatum
- 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.
- b DNA "double helix"
- c is antiparallel with a 5'prime end and a 3'prime end
- d Neurospora research, experiment on fungus and mold - "one gene one enzyme"
- e Models of Replication; Conservative, semiconservative, disruptive/dispersive
5 Multiple choice questions
- the rough strand
- 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.
- untwists the double helix at the replication forks
- "T", Thymine
- bead-like structures with 140 base pairs of DNA wrapped around a disc of eight histone proteins.
5 True/False questions
P Region → is the small region of a chromosome "petite"
Transformation → is the large region of a chromosome
DNA Polymerase → installs new nucleotids; catalyzes the snythesis of new DNA by adding nucleotides to a pre-existing chain.
Topoisomerase → and enzyme that adds segments to ends of molecules of DNA/seals the ends acts like bumpers.
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.
