Question

Protein synthesis in an animal cell takes place in ________

• A. Cytoplasm
• B. Ribosomes attached to the nucleus
• C. Both in the nucleolus and in the cytoplasm
• D. both in the cytoplasm as well as in mitochondria

Answer 1

The correct option is D

both in the cytoplasm as well as in mitochondria

The correct option is D.

The explanation for the Correct option:

1. Ribosomes are used in the production of proteins.
2. The cytoplasm contains ribosomes.
3. Transcription is the process by which the DNA in the mitochondria and nucleus creates the RNA.
4. The RNA created serves as a template for the creation of proteins.
5. The RNA is then converted into a nascent protein and transported to the cytoplasm, where it undergoes additional functional modifications.
6. The cytoplasm and mitochondria both contain the RNA template and ribosomes, two crucial parts.

The explanation for the Incorrect option:

Option A:

1. The cytoplasm contains only ribosomes.
2. RNA is not present in the cytoplasm

Option B:

1. Ribosomes are not attached to Nucleus.
2. They are attached to the rough endoplasmic reticulum of the cell.

Option C:

1. The nucleolus does not hold the RNA strand.
2. That is the Nucleus, which can support protein synthesis because it carries RNA and the cytoplasm of the cell contains ribosomes.

Final Answer:

Protein synthesis in an animal cell takes place in both, the cytoplasm as well as in mitochondria.
