Evolution-Of-Life Question 55
Question: Most biologists think that RNA was the first genetic material because:
Options:
A) Amino acids were produced in Stanley Miller’s apparatus.
B) DNA is the universal genetic material of eukaryotes.
C) Existence of ribozymes suggests RNA was used to catalyse chemical reations.
D) RNA is simpler than DNA.
Show Answer
Answer:
Correct Answer: C
Solution:
Option C is correct because ribozymes are RNA molecules that can catalyze chemical reactions, similar to the way proteins (enzymes) catalyze reactions. This suggests that RNA can both store genetic information (like DNA) and catalyze biochemical reactions (like proteins). This dual functionality of RNA supports the hypothesis that RNA could have been the first genetic material and might have played a central role in early life forms before DNA-based replication systems evolved.
