4.NUCLEIN

Answer 1

2)RNA is right answer.

Answer 2

RNA is the the 1st genetic material.
Evidences suggest that essential life process such as metabolism , splicing , translation , etc, evolved around RNA .
RNA used to act as genetic material as well as a catalyst and being a catalyst it was reactive and hence unstable.
Therefore , DNA has evolved from RNA with chemical modifications.
Hence, RNA is the first genetic material.
