Question

Did DNA or RNA come first and why? (ORIGIN OF INFORMATION SYSTEM)

A) DNA; Greater stability and hereditary information storage
B) RNA; Simplicity and versatility in catalysis and information storage
C) Both emerged simultaneously; Co-dependent functions in early cells
D) Neither; Information systems evolved differently in distinct organisms

Answer 1

The RNA world hypothesis suggests that RNA may have come first in the evolution of information systems. RNA is a versatile molecule that can encode genetic instructions and carry out chemical reactions. While DNA provides greater stability and hereditary information storage, RNA's simplicity and versatility make it a strong candidate for coming first.

Step-by-step explanation:

The origin of DNA and RNA and which came first is a subject of scientific debate. The RNA world hypothesis suggests that RNA may have been the first organic molecule to evolve, and early life may have been based solely on RNA. RNA can encode genetic instructions like DNA and carry out chemical reactions like proteins, making it a versatile molecule. While DNA provides greater stability and hereditary information storage, RNA's simplicity and versatility in catalysis and information storage make it a strong contender for coming first in the evolution of information systems.
