Question Detail
Question
The unity among all organisms can be attributed to: a. natural selection b. life and forms of organisms c. the structure and function of DNA d. emergent properties
Correct Answer
Option C is the correct answer.
Detailed Explanation
The near-universal structure and function of DNA (the genetic code) is a powerful example of unity among all organisms. It points to a common origin for all life. Natural selection explains diversity, not necessarily unity.
Hint
All life uses the same basic molecule to store and transmit genetic information.
