Chargaff Mirsky A T G C Somatic cells in each species have similar amounts of DNA The consistency of DNA Used radioactive labeling to trace the DNA and protein Concluded that the viral DNA was injected into the cell and Hershey and Chase Avery provided the genetic information needed to produce new viruses Identified the molecule that transformed the R strain of bacteria into the S strain Concluded that when the S cells were killed DNA was released R bacteria incorporated this DNA into their cells and changed into S cells Watson and Crick research Built a model of the double helix that conformed to the others o Two outside strands consist of alternating deoxyribose and phosphate hydrogen bonds hydrogen bonds o Cytosine and guanine bases pair to each other by three o Thymine and adenine bases pair to each other by two What is bacterial transformation The process by which bacterial cells take up naked DNA molecules What bases are found in DNA DNA is synthesized in what direction The strands of the DNA double helix are parallel or antiparallel What does that mean What type of bond is involved in base pairing What untwists the double helix What is the primer that initiates DNA synthesis What enzyme ends in ase synthesizes the primer What is an Okazaki fragment Adenine A cytosine C guanine G thymine T The same direction as the growing replication fork Antiparallel They go in opposite directions Hydrogen bonding Helicase Primase DNA polymerase A short newly synthesized DNA fragment that is formed on the lagging template strand during DNA replication
