Question

The replication of DNA molecules requires serveral different enzymes, all of which require specific environmental conditions in order to maintain a functional shape. Hypotheses about the origin of life on Earth pose that before self-replicating genetic information evolved, a protobiont emerged similar to a cell membrane that separated genetic material from external environments.
The formation of which of the following organic molecules would have facilitated the formation of structures capable of maintaining isolated, internal microenvironments different from external environmental conditions?

• A. Proteins
• B. Lipids
• C. RNA molecules
• D. Ribozymes

Answer 1

The correct option is C RNA molecules

RNA is believed to be the first genetic material. This primitive RNA, however short and simple, was able to duplicate themselves, catalyze the process, as well as splice their own introns. As RNA grows more in size and complexity, it acquires the ability to fold itself. The rate of mutations also increases as the fidelity of RNA becomes lower due to the ever-growing compilation. Because of RNA's domination in the field of inheritable information.

So, the correct answer is " RNA Molecules".
