Question

Scientists have estimated that the total number of DNA bases in humans is approximately:

• A. 1.4 billion
• B. 3164.7 million
• C. 6 x 10$^9$
• D. 3 x 10$^9$

Hint:

The human genome contains approximately 6 billion base pairs, which form the complete set of instructions for human life.

Answer 1

The Correct Option is C

Step 1: Understanding the Question.
The question is about the total number of DNA bases in the human genome.

Step 2: Analyzing the Options.
(A) 1.4 billion: This is incorrect, as the total number of bases is much higher.
(B) 3164.7 million: This is incorrect, as this is a rough estimate, but the actual number is around 6 billion bases.
(C) 6 x 10$^9$: Correct — The human genome consists of approximately 6 billion base pairs.
(D) 3 x 10$^9$: This is too low compared to the actual value.

Step 3: Conclusion.
The correct answer is (C) 6 x 10$^9$, which represents the total number of DNA base pairs in the human genome.
