A typical human chromosome contains _ nucleotides in its DNA:
Correct answer: C. 140 million
- A. 240 million
- B. 150 million
- C. 140 million
- D. 160 million
Explanation
A typical human chromosome contains 1.4x108 nucleotides in its DNA. The amount of information one chromosome contains would fill about 280 printed books of 1000 pages each if each nucleotide corresponds to a word and each page has 500 words on it.
