It is convenient to divide the photosynthetic process in plants into four stages, each occurring in a defined area of the chloroplast: (1) absorption of light, (2) electron transport leading to the reduction of NADP+ to NADPH, (3) generation of ATP, and (4) conversion of CO2 into carbohydrates (carbon fixation).
DNA is important because it is a molecule that encodes the genetic instructions used in the development and functioning of every living thing.
DNA replication is important because cells multiply through replication, and if DNA could not replicate then cell replication would not be possible. This is important for growth and healing.
Without DNA and DNA replication almost all living organisms would not exist.
