"The consistency of $DNA$ copying during reproduction is important for the maintenance of body design features." Support this statement with two arguments.

(N/A) $(i)$ $DNA$ copying is essential for the formation of additional cellular apparatus, ensuring that when $DNA$ copies separate, each daughter cell receives its own complete set of cellular machinery.
$(ii)$ The process of $DNA$ copying is not perfectly accurate and results in minor variations each time. Consequently, while the generated $DNA$ copies are similar to the original, they may not be identical, which allows for evolution and adaptation over generations.
