What will be the approximate length of a DNA strand having 500 nucleotides?
Correct answer: C. 170 nm
- A. 100 nm
- B. 130 nm
- C. 170 nm
- D. 150 nm
Explanation
Assuming that each nucleotide is 0.34 nm in length, the length of a DNA strand with 500 nucleotides would be approximately: 500 nucleotides x 0.34 nm/nucleotide = 170 nm. Therefore, the answer is option (c) 170nm.
