Question

When we talk of functional macromolecules (e.g. proteins as enzymes,hormones, receptors, antibodies etc), towards what are they evolving?

Answer 1

Chemical evolution:

According to chemical evolution macromolecules have evolved from smaller inorganic molecules due to the primitive atmospheric earth conditions.



Theory of biogenesis:

The theory of biogenesis states that these macromolecules formed were self-sustaining non cellular units and were the precursor for the first cell that was formed.
