Question
If Meselson and Stahl's experiment is continued for four generations in bacteria, the ratio of `15_N/15_N:15_N/14_N:14_N/14_N` containing DNA in the fourth generation would be ______.
Options
0 : 1 : 7
0 : 1 : 3
1 : 4 : 0
1 : 1 : 0
Solution
If Meselson and Stahl's experiment is continued for four generations in bacteria, the ratio of `15_N/15_N:15_N/14_N:14_N/14_N` containing DNA in the fourth generation would be 0 : 1 : 7.
