the eukaryotic cell's genetic instructions are housed in the nucleus and carried out by the ribosomes
ribosome - structure is two subunits made of ribosomal RNAs and proteins; can be free in cytosol or bound to ER
function- protein synthesis
nucleus/ER- structure is surrounded by nuclear envelope (double membrane) performed by nuclear pores; nuclear envelope continuous with endoplasmic reticulum (ER)
function- houses chromosomes, which are made of chromatin (DNA and proteins); contains nucleoli, where ribosomal subunits are made; pores regulate entry and exit of materials
