Why rna and not dna was the first living molecule from 1 mark

Answer 1

Answer:

It now seems certain that RNA was the first molecule of heredity, so it evolved all the essential methods for storing and expressing genetic information before DNA came onto the scene. However, single-stranded RNA is rather unstable and is easily damaged by enzymes.

Because the first living organisms had a very simple cell machinery.

Thus they used rna as a genetic material as well as enzyme.

RNA can act as an enzyme because of its unstable nature.
