Question

according to the dna-rna hybrid hypothesis, what was the primary advantage of adding dna building blocks to an rna strand?

it allowed the molecule to absorb more sunlight.

it allowed the molecule to move faster in water.

it made the molecule more stable and less likely to break down.

it made the molecule easier for viruses to infect.

Explanation:

To solve this, we analyze each option based on the DNA - RNA Hybrid Hypothesis. DNA is more stable than RNA. Absorbing more sunlight (first option) is not related to adding DNA building blocks to RNA. Moving faster in water (second option) is not a property related to this modification. Making the molecule easier for viruses to infect (fourth option) is incorrect as stability is the key here. The correct reason is that DNA building blocks make the molecule more stable and less likely to break down.

Answer:

C. It made the molecule more stable and less likely to break down.
