Final answer:
The centrosome and replication of DNA are produced in the initial growth stage of the cell cycle.
Step-by-step explanation:
In the initial growth stage of the cell cycle, two main structures are produced: the centrosome and the replication of DNA.
The centrosome is responsible for organizing and separating the chromosomes during cell division.
Replication of DNA ensures that each new cell receives an identical copy of the genetic material.
