Protein synthesis (1 of 3): overview (bioflix tutorial) in eukaryotic cells, the nuclear dna codes for the synthesis of most of the cell's proteins. each step of protein synthesis occurs in a specific part of the cell. in addition, various forms of rna play key roles in the processes of protein synthesis. before beginning this tutorial, watch the protein synthesis animation. pay particular attention to the cellular locations where the various steps of protein synthesis occur in eukaryotic cells, as well as the different types of rna and how they function. part a - locations of the processes involved in protein synthesis in eukaryotic cells, the processes of protein synthesis occur in different cellular locations. drag the labels to the appropriate targets to identify where in the cell each process associated with protein synthesis takes place.
