The Human Genome Project determined the sequence of roughly how many base pairs?
Correct answer: B. 3 billion
- A. 3 million
- B. 3 billion
- C. 300 thousand
- D. 3 trillion
Explanation
Completed in 2003, the project read about three billion base pairs spanning the human genome's roughly 20,000 to 25,000 genes. Confusing billions of bases with thousands of genes is the trap.
