Question

Which of the following is the co-factor for origin of life from pre-RNA?

• A. ATP
• B. Acetyl-coA
• C. NADH
• D. All of the above

Answer 1

Answer: (D)

All of the above

The RNA world is a hypothetical stage that considers the RNA as the genetic material and also states that all the important metabolic processes revolve around the RNA.

Like DNA, RNA can store and replicate genetic information; like protein enzymes, RNA enzymes (ribozymes) can catalyze chemical reactions.

One of the most critical components of cells, the ribosome, is composed primarily of RNA. Ribonucleotide moieties in many coenzymes, such as Acetyl-CoA, NADH, FADH are found that support the RNA world hypothesis.

So, the correct option is 'All of the above'
