DNA is copied during replication

C

Explanation:

Replication is the process by which a double-stranded DNA molecule is copied to produce two identical DNA molecules.To accomplish this, each strand of existing DNA acts as a template for replication.

the nitrogen cycle provides nitrogen to the ecosystem from the atmosphere, ground and oceans. nitrogen is an important component of complex molecules such as amino acids and nucleotides, which lead to the creation of proteins and dna, the building blocks of all life. plants absorb nitrogen in the form of ammonium, nitrate ion and, on rare occasions, as amino acids. animals receive nitrogen necessary for biological processes from feeding on living or dead organic matter.
