The correct answer for this question is (D) It can proceed in the dark.

Calvin cycle is named after Melvin C. Calvin, who won a Nobel prize in chemistry for finding it in 1961. Calvin cycle take place in chloroplasts during photosynthesis and it is a <u>light-independent reaction so also called as dark reaction.</u>

The Calvin cycle proceeds in three stages:

1. Carboxylation, during which CO2 combines with ribulose-1,5- bisphosphate

2. Reduction, during which carbohydrate is formed at the expense of photochemically made ATP and NADPH

3. Regeneration during which the CO2 acceptor ribulose-1,5- bisphosphate is formed again so that the cycle continues.

DNA is a negatively-charged molecule. Also cell membranes are negatively charged. The problem would be how to push this charges together? I<span>f you put some CaCl2 into the mixture, the CaCl2 will "split" giving 2Cl- and Ca2+. This last ion will be attracted by the negatively charged DNA and will "cover" it, hiding its negative charge. Hope this answers the question.</span>
