Which was Likely the First Molecule of Life

Question

Which was likely the first molecule of life?
A)DNA
B)RNA
C)protein
D)lipids

Accepted Answer

RNA is believed to be the first molecule of life as it has the ability to self-replicate, act as a catalyst, and store genetic information, which are all important properties for the origin of life. RNA can also form spontaneously under conditions that could have existed on early Earth. While DNA is essential for life today, it is thought to have evolved from RNA. Proteins and lipids are important components of life, but they are not believed to have been the first molecules to appear.
