Afterwards, the hybrid groups were incubated in pure 14N which resulted in one strand being a hybrid and the other being pure 14N ultimately depicting the semi-conservative model.]]> 2017-02-09 14:50:53 UTC https://padlet.com/perkins2/jrfj2wxr28k2/wish/152790117 Akshita and Quincy https://padlet.com/perkins2/jrfj2wxr28k2/wish/152791349 The semi-conservative is the most plausible model because there isn't a really separation of 15N and 14N in the test tubes]]> 2017-02-09 14:53:52 UTC https://padlet.com/perkins2/jrfj2wxr28k2/wish/152791349 Kristin, Madi, Kelsey kr1060653 https://padlet.com/perkins2/jrfj2wxr28k2/wish/152791413 semi conservative because there's half new and half old dna present.]]> 2017-02-09 14:54:00 UTC https://padlet.com/perkins2/jrfj2wxr28k2/wish/152791413 Julia and Ethan js13812 https://padlet.com/perkins2/jrfj2wxr28k2/wish/152791774 semi conservative,
It couldn't be conservative, since the DNA molecules created from the 14N and 15N are a mix of both. So it cannot be conservative because it makes an entirely new copy with no mix. and It cannot be dispersive because if it were, there would be one hybrid band in the center. ]]> 2017-02-09 14:54:56 UTC https://padlet.com/perkins2/jrfj2wxr28k2/wish/152791774 Jacob & Brent https://padlet.com/perkins2/jrfj2wxr28k2/wish/152792724 Semi-Conservative 
There would be one hybrid band in the middle of the tube.
