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.

"-the movement of carbon from the nonliving environment into living things and back to the environment

-carbon is the essential component of proteins, fats, and carbohydrates (which make up all organisms)

-carbon exists in air, water, and living organisms

-producers convert carbon dioxide in the atmosphere into carbohydrates during photosynthesis

-bacteria in the atmosphere cycles through the system in filtration units

-in cellular respiration, carbon is released back into the atmosphere as carbon dioxide

-some carbon is stored in limestone (forming one of the largest "carbon sinks" on earth)

-largest carbon reservoir on earth= limestone

-carbon stored in the bodies of organisms as fat, oils, or other molecules may be released into the soil or air when the organism dies

-this may form deposits of coal, oil, or natural gas (fossil fuels, which increased the atmospheric carbon dioxide)

-fossil fuels store carbon left over from bodies of organisms that died millions of years ago

-they are located in the surface of earth, deep within the earth and beneath the ocean floor."
