Question
Chapter 4, Problem 18P
Interpretation Introduction
Interpretation:
Why is DNA synthesis performed in 51-31 direction?
Concept introduction:
51 and 31 indicate the number of carbon in DNA sugar backbone. A 51 carbon has phosphate group whereas a 31 carbon has hydroxyl group. The direction of DNA strand is given by this 51 and 31 asymmetry.

Backward? Bacteriophage T7 helicase moves along DNA in the 5'-to-
3'5'-to-3' direction. Other helicases have been reported to move in
the 3'-to-5'3'-to-5' direction. Is there any fundamental reason why
you would expect helicases to move in one direction or the other?
Read and analyze the question and choices CAREFULLY; more importantly, ALWAYS CHOOSE the BEST answer.
How are deoxyribonucleoside triphosphates (precursors of daughter DNA strands) and ribonucleoside
triphosphates (precursors of RNA strand) differ from each other?
O A. Deoxyribonucleoside triphosphates have an additional sugar residue at the 2' carbon (carbon number 2) in its
deoxyribose. Meanwhile, an amino acid residue is not attached at the 2' carbon of ribonucleoside triphosphates in its
ribose.
O B. Deoxyribonucleoside triphosphates have an oxygen atom at the 2' carbon (carbon number 2) in its deoxyribose.
Meanwhile, an oxygen atom is not attached at the 2' carbon of ribonucleoside triphosphates in its ribose.
OC Deoxyribonucleoside triphosphates have an amino acid residue at the 2' carbon (carbon number 2) of in
deoxyribose. Meanwhile, an oxygen atom is not attached at the 2' carbon of ribonucleoside triphosphates in its
ribose.
OD. Deoxyribonucleoside triphosphates do not have…
