Question

Due to the discovery of which of the following in 1980, the evolution was termed as RNA world?

• A. mRNA, tRNA, rRNA synthesize proteins
• B. In some virus RNA is genetic material
• C. RNA have enzymatic property
• D. RNA is not found in all cells

Answer 1

The correct option is C RNA have enzymatic property

Like DNA, RNA can also store genetic information and replicate itself. Self-replicating RNA molecules proliferated even before the discovery of DNA and proteins. But some RNA enzymes, known as ribozymes, can start or accelerate chemical reactions that are critical for life sustenance. This lead to the evolution of the RNA world hypothesis.

So, the correct option is 'RNA have an enzymatic property'.
