Carbon dioxide is fixed into glucose during carbon ?

Answer:
Carbon fixation during photosynthesis
Explanation:
Photosynthesis is the process through which plants synthesise carbohydrates using light energy from the sun. The overall equation is
CO2 + H20 + (energy) → glucose + oxygen
Photosynthesis can be split into two stages: The light-dependent reactions, and the light-independent reactions. Carbon fixation (sometimes called the Calvin cycle) is part of the light independent reactions
During carbon fixation, carbon dioxide is incorporated into a 5 carbon sugar called RuBP. This immediately forms two molecules of 3-PGA, which is converted into G3P. Some of the G3P is used to synthesise sugars, and the rest is used to regenerate RuBP.

The question is incomplete. The complete question is attached below.
Answer:
1. DNA is the polymer of deoxyribonucleotides that contain the nitrogenous base, pentose sugar and phosphate group. The phosphate is attached with the 3 C position of the deoxyribose sugar. This leads to teh formation of phosphodiester bond.
2. The DNA backbone consists of phosphate and sugar. The nitrogenous bases are inserted inside the DNA molecule. These nitrogenous bases are linked together by the hydrogen bonds.
3. The adenine binds requires two hydrogen bonds to bind with thymine. This provide complementary nature to the DNA molecule. Uracil is present instead of thymine in RNA .
4. The guanine binds requires three hydrogen bonds to bind with cytosine. More amount of energy is required to break their bonds.
