Question

Which of the following properties could help RNA be both an information storage unit and a self-replicating molecule?

A. RNA can act as a template for making copies of itself.

B. RNA is a short-lived molecule.

C. RNA cannot catalyze reactions.

D. RNA must be made from DNA.

Answer 1

RNA can act as a template for self-replication, RNA can have catalytic activity, RNA is single stranded.

Step-by-step explanation:

The properties of RNA that allow it to be both an information storage unit and a self-replicating molecule are:

1. RNA can act as a template for making copies of itself: RNA molecules can serve as a template for the synthesis of new RNA molecules through a process called transcription. This allows RNA to self-replicate, making more copies of itself.
2. RNA can have catalytic activity: Some RNA molecules, called ribozymes, have catalytic activity and can perform chemical reactions. This allows RNA to not only store genetic information but also carry out important functions within the cell.
3. RNA is single stranded: Unlike DNA, which is double stranded, RNA is single stranded. This makes it more flexible and allows it to fold into different shapes, which is important for its function as both an information storage unit and a self-replicating molecule.
