Statement I: RNA being a catalyst was reactive and hence unstable.
Statement II: DNA being double stranded and having complementary strand further resists changes by evolving a process of repair.
In the light of the above statements, choose the correct answer from the options given below.
Statement II: DNA being double stranded and having complementary strand further resists changes by evolving a process of repair.
In the light of the above statements, choose the correct answer from the options given below.
