BIOXII06: MOLECULAR BASIS OF INHERITANCE

342990 In Messelson and Stahl's experiment
Statement A :
\({ }^{15} \mathrm{~N}\) was incorporated into newly synthesised RNA only
Statement B :
The DNA that was extracted from the culture one generation after the transfer from \({ }^{15} \mathrm{~N}\) to \({ }^{14} \mathrm{~N}\) medium [that is after 20 minutes; E. coli divides in 20 minutes] had \(\mathrm{N}^{14} \mathrm{~N}^{14}\)
