BIO 181 ASU Unit 5DNA as hereditary material- Griffith - correct answer Griffith worked with two strands of Streptococcus Pneumoniae. One virulent strand and 1 non virulent strand. Results of mouse test - correct answer Found that the benign strand + the heat killed virulent strand still killed the mouse. Griffith found that heat-killed virulent S. pneumonia cells could transform a nonvirulent rough strain into a smooth virulent strain. He called this transformation Is protein, DNA, or RNA...

Who performed classic experiments that supported the semiconservative model of DNA replication? - Meselson and Stahl What separates the DNA strands during replication? - helicase A new DNA strand elongates only in the 5' to 3' direction because - DNA polymerase can only add nucleotides to the free 3' end. What is the role of DNA ligase in the elongation of the lagging strand during DNA replication? - It joins Okazaki fragments together
