Translation occurs on ribosomes, which may be free in the cytosol (producing cytosolic proteins) or bound to rough endoplasmic reticulum (producing secreted or membrane proteins). Thus B is correct. Transcription (A) occurs in the nucleus, where DNA is transcribed to pre-mRNA; it is then processed (capping, splicing, polyadenylation) and exported to the cytoplasm for translation. Glycolysis (C) takes place in the cytosol, not the mitochondrial matrix; the matrix hosts the citric acid cycle and pyruvate dehydrogenase. DNA replication (D) also occurs in the nucleus during S phase, not in the Golgi; the Golgi apparatus modifies and sorts proteins and lipids for trafficking. TEAS frequently assesses organelle–function mapping: nucleus (DNA, transcription), ribosomes (translation), rough ER (secretory pathway), smooth ER (lipids/detox), Golgi (processing/sorting), mitochondria (ATP generation via TCA/ETC), cytosol (glycolysis). Knowing these pairings prevents common distractor traps that move nuclear processes into the cytoplasm or assign metabolic pathways to incorrect organelles.
