During DNA renaturation, two DNA strands will:

a. break the hydrogen bonds that hold the two strands together with no effect on the covalent bonds that hold the nucleotides together.
b. break the covalent bonds that hold the nucleotides together while maintaining the hydrogen bonds that hold the two strands together.
c. Re-form a double helix if the two strands have complementary sequences.
d. Re-form a double helix if the two strands are identical in sequence.

Me i need this asap during photosynthesis, the following reaction takes place: carbon dioxide + water + light energy → sugar + oxygen during cellular respiration, the following reaction takes place: sugar + oxygen → carbon dioxide + water + chemical energy given this information, how are photosynthesis and cellular respiration related? question 2 options: the products of photosynthesis are the reactants of cellular respiration. photosynthesis and cellular respiration both start with the same materials. photosynthesis and cellular respiration both produce the same materials. the same type of energy is found in both photosynthesis and cellular respiration.
