BIOL 1107 Chapter Notes - Chapter 14: Enterobacteria Phage T2, Streptococcus, Semiconservative Replication
Document Summary
Be able to explain how the bacterial transformation experiments supported the hypothesis that. Be able to explain how the t2 phage experiments provided evidence that dna, not proteins, is the genetic material of cells. Understand what the semi-conservative model of dna replication implies about the composition of how dna is assembled. Be able to describe the functions of the enzymes of dna replication. Transformation ~ the alteration of a cell"s hereditary type by the uptake of dna released by the breakdown of another cell. Virus ~ an infectious agent that consists of either dna or rna surrounded by a protein coat. Griffith found a substance that could transform pneumonia bacteria genetically. Avery and his coworkers identified dna as the molecule that transforms nonvirulent. Hershey and chase obtained the final experimental evidence establishing dna as the. Imagine that 35s labeled both protein and dna, whereas 32p labeled only dna.
