They also found that TRIM25 (previously believed to be present only in the cell cytoplasm) is also present in the cell nucleus, which is the same cellular location where flu replication occurs.

Autophagy is a dynamic, multi-step process that starts with the formation of a double - membrane sac in the cell cytoplasm called the isolation membrane (IM).

But if they misfold, the proteins are ejected from the ER back into the cell cytoplasm, where they are tagged and then destroyed by agglomerations of other proteins.

Copies of the DNA exit the nucleus to be read and translated into proteins in the cell cytoplasm.

They both replicate in the cell cytoplasm, and on doing so, each uses the same machinery within the cytoplasm to form a new membrane around itself.

MinE activates the enzymatic activity of membrane - bound MinD, thus triggering the conversion of its bound nucleotide adenosine triphosphate (ATP) to adenosine diphosphate (ADP), which causes the release of MinD - ADP into the cell cytoplasm.

The instructions for the synthesis of proteins are stored in the DNA in the cell nucleus, are first «transcribed» into mRNAs, and exported from the nucleus to the ribosomes in the cell cytoplasm.
