RNA has the ability to catalyze chemical reactions
B
RNA is extremely stable
C
RNA can fold into complex 3D shapes
D
RNA can store information
E

Verified step by step guidance1
Understand the concept of the 'RNA world hypothesis,' which suggests that RNA was a fundamental molecule in early life forms due to its ability to both store genetic information and catalyze chemical reactions.
Consider the property of RNA's ability to catalyze chemical reactions (option a). This is significant because it suggests RNA could have played a role similar to enzymes, which are proteins, in early life forms.
Evaluate the stability of RNA (option b). RNA is generally less stable than DNA, which is why DNA is used for long-term storage of genetic information in most organisms today.
Examine RNA's ability to fold into complex 3D shapes (option c). This property is crucial for its catalytic activity, similar to how proteins fold into specific shapes to function as enzymes.
Assess RNA's capability to store information (option d). This is a key feature that supports the idea of RNA being a precursor to DNA, as it can carry genetic information necessary for life processes.
