Question

.1/7 origins of dna/rna (dg)

the discovery of ribozymes supports the rna world hypothesis because it proves that rna can:

act as a catalyst to speed up chemical reactions.

transform into gold when heated.

survive in the freezing temperatures of outer space.

only store information but not perform any work.

Explanation:

The RNA World Hypothesis suggests RNA was the first self - replicating entity with catalytic properties. Ribozymes are RNA molecules with catalytic activity. Catalysts speed up chemical reactions. The option "Transform into gold when heated" is scientifically impossible for RNA. RNA's survival in outer space temperatures isn't related to ribozymes' support of the hypothesis. RNA can both store information and perform work (like catalysis), so the "only store information" option is wrong. So ribozymes show RNA can act as a catalyst.

Answer:

A. Act as a catalyst to speed up chemical reactions.
