Q. In an electric field, if an amino acid migrates towards cathode, the pH of the solution is said to be
A) Less than pI
B) More than pI
C) Equal to pI
D) 7
Explanation
(a)
Cations move towards cathode and when pH<pl, thus catonic form dominates
Thus, percentage of radioactive DNA after second replication is 50%
