SUMMARY
The collective term for molecules involved in protein synthesis, encompassing both translation and transcription, is referred to as "protein synthetic machinery." In eukaryotic cells, transcription is executed by RNA polymerase II, a multiprotein complex that operates in the nucleus, while translation occurs in the cytoplasm via the ribosome, a large protein-RNA complex. The replisome, which is responsible for DNA replication, differs from the protein synthetic machinery as it forms a complex of proteins that act simultaneously, whereas transcription and translation are compartmentalized processes. Understanding these distinctions is crucial for comprehending cellular functions.
