Sugars link together by phosphates to create the backbone of the DNA or RNA molecule. Genetic information is carried and stored in the sequence of nucleic acid bases along a chain of DNA or RNA. When cells duplicate inside of the human body, DNA is replicated through RNA in order to give the new cell a new set of DNA.
Hope this helped! :)

The answer is chloroplasts and mitochondria.
<span>When solar energy in the form of sunlight reaches a leaf of a plant, it passes through the leaf to chloroplasts. Chloroplasts contain pigment chlorophyll which is excited by light. As the result, </span>a series of chemical reactions occur in the chloroplasts and carbon dioxide and water are converted into glucose and oxygen. Now, glucose is broken down and transported into mitochondria where through different processes (Krebs cycle and electron transport chain) energy is produced in the form of ATP.<span>
