Answer:
the citric acid cycle and preparatory steps
Answer: Helicase
Explanation: Replication is a process of making two identical copies of DNA from a double-stranded DNA. This process is catalyzed by an enzyme called DNA polymerase. Before DNA polymerase begins the synthesis of the new strands, helicase will unwind or unzip the double-stranded DNA. Helicase is the enzyme that unzips or unwinds the double-stranded DNA helix during replication. Helicase separates the two strands by moving along the DNA using chemical energy from ATP. The separated strands serve as templates for the synthesis of new DNA strand.
Energy from the sun sets in motion both the carbon and water cycles. Recall that sunlight plus water plus carbon dioxide are combined by photosynthesis in green plants to create carbohydrates. However, changes to the carbon cycle can have an impact upon the water cycle.
