In many eukaryotic cells, DNA stored in the nucleus is transcribed into messenger RNA. The mRNA is then transported into the cytoplasm where ribosomes assist in their translation into proteins. Finally, these proteins are packaged and sorted in the Golgi apparatus for use in other parts of the cell or in preparation for secretion into other cells. Which of the following statements is supported by this description?
a. Various organelles within a cell interact with each other to carry out life processes.
b. Organelles within a cell act independently of each other at all times.
c. Some organelles are more important than other organelles within a cell.
d. Only up to three organelles may interact with each other at any given moment in time.
