Which of the Following Helps Support the RNA World Hypothesis

Question

Which of the following helps support the RNA World hypothesis?
A)ribozymes
B)catalytic RNAs
C)genetic information encoded on RNA
D)all of the above

Accepted Answer

The RNA World hypothesis proposes that RNA molecules were the earliest form of genetic material and played a central role in the origin of life. Ribozymes and catalytic RNAs are RNA molecules that catalyze chemical reactions, providing evidence that RNA can have enzymatic activity. Genetic information can also be encoded on RNA, supporting the idea that RNA could have been responsible for the origin of life. Therefore, all of the choices (A, B, and C) help support the RNA World hypothesis.
