Location of nucleotide synthesis and transport
Correct, all but one step in pyrimidine synthesis occurs in the cytosol, and purine synthesis occurs in the cytosol only. 

Nucleotides freely diffuse through nuclear pores but are actively transported through mitochondrial membranes via embedded membrane transport proteins (i.e. ATP-ADP translocators, GTP transporters, and pyrimidine nucleotide transporters).
