Answer #1

The answer is option A (RNA had both catalytic and information storing activities).

Explanation:

The RNA world hypothesis proposes that life-based on ribonucleic acid (RNA) predates the current world of life-based on deoxyribonucleic acid (DNA), RNA and protein. RNA is able to both store genetic information, like DNA, and catalyzes chemical reactions, like an enzyme protein. hence It may have supported pre-cellular life and been the first step in the evolution of cellular life.

    2) Drosophila muscleblind (Mbl) is an RNA binding protein necessary for early development of null flies in the late embryo stages. The same class of proteins, the MBNL proteins, have been shown to play an important role in myotonic dystrophy in humans. During a study, various RNA sequences were added to Mbl to determine if common structural characteristics arose in structures that showed strong binding characteristics to the protein. Below are two RNA structures that showed strong bonding characteristics (12...
