Final answer:
The statement in the question is false. Only some of the nuclear DNA binding transcription factors are synthesized by the ribosomes of the RER, while others are synthesized by the cytoplasmic ribosomes.
Step-by-step explanation:
The statement in the question is false. Only some of the nuclear DNA binding transcription factors are synthesized by the ribosomes of the rough endoplasmic reticulum (RER), while others are synthesized by the ribosomes in the cytoplasm.
Ribosomes are the cellular structures responsible for protein synthesis. In eukaryotic cells, ribosomes can be found in the cytoplasm as well as on the surface of the RER. The RER-bound ribosomes produce proteins that are destined for secretion or specific organelles.
