Transcription takes place in the ______ and translation takes place ______
nucleus; in the cytoplasm at the ribosomes
nucleus; in the cytoplasm at the golgi apparatus
in the cytoplasm at the ribosomes; in the nucleus
in the cytoplasm at the ribosomes; in the rough endoplasmic reticulum
The Correct Answer is A
A. nucleus; in the cytoplasm at the ribosomes
Transcription is the process of converting DNA to mRNA and occurs in the nucleus. Translation is the process of reading mRNA to synthesize proteins and occurs at the ribosomes, which are located in the cytoplasm (either free-floating or bound to rough ER).
B. nucleus; in the cytoplasm at the Golgi apparatus
Transcription occurs in the nucleus. But translation does not occur at the Golgi apparatus. The Golgi modifies, packages, and ships proteins, but does not synthesize them.
C. in the cytoplasm at the ribosomes; in the nucleus
This reverses the correct locations. Transcription is not in the cytoplasm, and translation is not in the nucleus.
D. in the cytoplasm at the ribosomes; in the rough endoplasmic reticulum
Transcription does not occur in the cytoplasm. While translation can occur on ribosomes attached to the rough ER, that’s a subset of ribosomes. The general location of translation is in the cytoplasm.

Correct Answer is D
Explanation
A. it is a decomposition dehydration reaction: Dehydration removes water, but this reaction adds water (H₂O).
B. it is an anabolic reaction: Anabolic reactions build larger molecules from smaller ones. This reaction is breaking a molecule apart.
C. it is an exchange reaction: Exchange reactions involve swapping parts between molecules—not just splitting.
D. it is a decomposition hydrolysis reaction: This is a decomposition (breaking down) reaction using hydrolysis (water added to break bonds).
E. it is a synthesis dehydration reaction: That would involve joining molecules together and removing water, which is not the case here.
Correct Answer is D
Explanation
A. 1,3,3,1,2,4: This order is illogical-it repeats pleura in an inconsistent pattern and places visceral pleura first.
B. 3,1,1,3,4,2: It ends with visceral pericardium followed by parietal, which is anatomically reversed.
C. 1,3,3,1,4,2: Starts with visceral instead of parietal and ends in the wrong order.
D. 3,1,1,3,2,4: This choice correctly represents the entry path: through parietal pleura (3) → visceral pleura (1) → lung → parietal pericardium (2) → visceral pericardium (4) → heart.
