Multiple Choice: For each multiple choice question, (1) choose which answer you believe to be correct and justify your
reasoning.
Then, explain why the other 3 answer choices are NOT correct.
Question 1: Figure 1 shows some relevant details of a model of how a deoxynucleotide, in this case dTMP, is added to a
growing strand of DNA.
The features of this model provide evidence for which explanation of why all growing strands are synthesized in a 5' to 3'
direction?
(A) The two strands need to be antiparallel to bond properly.
(B) Thymine and adenine would not bond properly if the strand grew from 3 to 5'.
(C) The translation of mRNA occurs in the 5' to 3' direction; therefore, the growing DNA strand must also grow in the
5' to 3' direction
(D) The phosphate group, attached to the 5' carbon of the TMP, forms a covalent bond with the oxygen atom
attached to the 3' carbon of the growing strand.
