Answer: Option A) DNA replication
Step-by-step explanation:
The term anabolism refers to any constructive metabolic process in which complex molecules such as nucleic acids are synthesized from simpler ones such as nucleotides, and it consumes rather than produce cellular energy.
Hence, unlike other options which describe breakdown of complex molecules, DNA replication involves the synthesis of nucleic acids (DNA or RNA) from simple repeating units of nucleotides complimentary to the parent strand.
Thus, DNA replication is an example of anabolism.
