Exploring Protein Synthesis: Transcription and Translation

The video tutorial by Amoeba Sisters explains the processes of transcription and translation, which are key steps in protein synthesis. Transcription occurs first in the nucleus, where RNA polymerase uses DNA to create mRNA. Translation follows outside the nucleus in ribosomes, where mRNA is used to assemble amino acids into polypeptide chains, forming proteins.

Where does transcription occur in eukaryotes?

• In the ribosome

• Outside the nucleus

• In the nucleus

• In the mitochondria

What enzyme is responsible for creating mRNA from a DNA template?

• DNA polymerase

• Ligase

• RNA polymerase

• Ribozyme

Where does translation take place?

• In the nucleus

• In the mitochondria

• In a ribosome

• In the cytoplasm

What is the role of tRNA in translation?

• To decompose ribosomes

• To synthesize mRNA

• To transfer amino acids

• To replicate DNA

What is the final product of connecting amino acids during translation?

• A lipid bilayer

• A polypeptide chain

• A ribosome

• A DNA molecule
