Question

protein synthesis is a two - part process.

• during the first part of protein synthesis, called transcription, genes are used as templates to create a special kind of rna molecule called messenger rna, or mrna. in eukaryotic cells, this process occurs in the nucleus.
• during the second part of protein synthesis, called translation, the mrna leaves the cell nucleus and travels to a ribosome, where it is used to assemble a protein.

complete the table to compare transcription and translation.

	transcription	translation
produces a protein	〇	〇
occurs in the nucleus of a eukaryotic cell	〇	〇
produces an mrna copy of a gene	〇	〇

Explanation:

1. For "Occurs at a ribosome": The text states translation happens at a ribosome, while transcription occurs in the nucleus.
2. For "Produces a protein": The text notes translation assembles a protein, while transcription produces mRNA.
3. For "Occurs in the nucleus of a eukaryotic cell": The text specifies transcription takes place in the eukaryotic nucleus, while translation happens at a ribosome outside the nucleus.
4. For "Produces an mRNA copy of a gene": The text defines transcription as creating mRNA from a gene template, while translation uses mRNA to make protein.

Answer:

	Transcription	Translation
Produces a protein	☐	☑
Occurs in the nucleus of a eukaryotic cell	☑	☐
Produces an mRNA copy of a gene	☑	☐
