From which did the beginning of life occur?
Think it through first, then pick an option.
- a Amino acid
- b Nucleic acid
- c Protovirus
- d Nucleoprotein
Answer and explanation
Correct answer: d Nucleoprotein
Nucleoprotein gained the power of replication and started life.
Why the other options are wrong
- a Amino acid: Amino acids join nucleic acids to make nucleoprotein; they do not start life alone.
- b Nucleic acid: Nucleic acid too is not alone; with amino acids it makes nucleoprotein.
- c Protovirus: Protovirus came after nucleoprotein. The right answer is Nucleoprotein.
