No, light dependent reaction does not depend on Calvin cycle.
Explanation:
Calvin cycle occurs in the second phase of photosynthesis i. e. light independent reaction. In this process, carbondioxide fixation takes place in the leaves of the plant. Light dependent reaction occurs first in which ATP and NADPH are produced which are used in Calvin cycle of light independent reaction for the production of sugar molecule such as glucose. So light dependent reaction does not depend on Calvin cycle.
There should be 22% Thymine because of Thymine pairs with Adenine, which on the table is shown to be 22%. (the complementary base pair are always equal). and the same would apply to Guanine (28%) and cytosine (28%).
