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 B
Explanation
A. an electron: An electron is a subatomic particle; it doesn’t retain the chemical properties of the element.
B. an atom: The atom is the smallest unit of an element that maintains its chemical identity and properties.
C. a chemical bond: A bond is the interaction between atoms, not a part of an element.
D. a proton: A proton is also a subatomic particle; it contributes to identity (atomic number) but isn’t an element by itself.
E. an orbital: An orbital is a region around the nucleus where electrons are likely to be found-it is not a unit of matter.
Correct Answer is D
Explanation
A. fluid: The cytosol is the fluid portion of the cytoplasm.
B. cytoplasmic inclusions: These include stored nutrients or pigments suspended in the cytosol (e.g., glycogen granules).
C. cytoskeletal elements: Elements like microfilaments and microtubules are found in cytosol and support cell shape and movement.
D. the nucleus: The nucleus is a separate organelle, surrounded by its own membrane, and is not part of the cytosol.
