Answer:

a) the pyrimidine ring is assembled before being bonded to the ribose phosphate, whereas the purine ring is bonded to the ribose phosphate as it is formed

Explanation:

There are two ways for the synthesis of purines and pyrimidines:

  1. de novo synthesis-from basic simple units
  2. "recycling" synthesis-reuse of metabolites

Purines are synthesized directly on ribose sugar, in segments.

Pyrimidines are attached to the ribose after the synthesis of the base.

This multi-cellularity is achieved through the property of called cellular differentiation and specialization. as the cellular complexity increases, therefore, cellular demands like the use of energy, food, water and other variables increased.

This lead to the formation of the organ and organs system specializes to perform specific functions like the digestive system and another biological system.
