Meselson and Stahl’s work on DNA replication takes an experimental approach, where some cells are grown in culture in the presence of radioactive nucleotides for many generations so that both strands of every DNA molecule include radioactive nucleotides. The cells are then harvested and placed in new medium with nucleotides that are not radioactive so that newly synthesized DNA will not be radioactive. (proportion) of DNA molecules (each molecule is double stranded not single stranded) will contain any radioactivity after two rounds of replication? This experiment also demonstrates that replication is.
a. 1/8; semiconservative
b. 1/8; dispersive
c. 1/4; conservative
d. 1/2; conservative
e. 1/2; semiconservative
