The 5' and 3' numbers are related to the

  • A.length of the DNA strand
  • B.carbon number in sugar
  • C.the number of phosphates
  • D.the base pair rule

Answer: B

Correct answer: carbon number in sugar

The primes refer to the carbon atoms of the deoxyribose, numbered 1’ to 5’ to distinguish them from the numbering of the base. The phosphate joins the 5’ carbon of one sugar to the 3’ carbon of the next, which is what gives each strand a direction.
