Replication is the copy of the cell's DNA when the cell divides.
Explanation:
Each double DNA helix chain is a template for the synthesis of a new complementary chain by DNA polymerases (enzymes that produce the new DNA), using a primer (initiator) and other necessary enzymes to continue the whole process.
Maybe not because after light increases stomas will decrease and after that plant leaf will take less co2 and less co2 mean less synthesis in the plant.
