Multiple Choice

Where in the cell does transcription occur?

• Nucleus

• Ribosome

Multiple Choice

Why is transcription considered an essential step in protein synthesis?

• Because it creates DNA

• Because it produces mRNA from DNA

• Because it breaks down proteins

• Because it occurs outside the cell nucleus

Multiple Choice

What is the role of transcription in protein synthesis?

• It copies DNA into mRNA, which is then used to create proteins.

• It copies mRNA into DNA, which is then used to create proteins.

• It copies proteins into DNA, which is then used to create mRNA.

• It copies DNA into proteins directly, skipping mRNA.
