Question
It is established that RNA is the first genetic material Explain
✓
Answer
→ RNA was the first genetic material.
→ There is now enough evidence to suggest that essential life processes (such as metabolism, translation, splicing, etc.), evolved around RNA.
→ RNA used to act as a genetic material as well as a catalyst (there are some important biochemical reactions in living systems that are catalysed by RNA catalysts and not by protein enzymes).
→ But, RNA being a catalyst was reactive and hence unstable.
→ Therefore, DNA has evolved from RNA with chemical modifications that make it more stable.
→ DNA being double stranded and having complementary strand further resists changes by evolving a process of repair.
