Protein Synthesis Processes and Functions

The video tutorial by Amoeba Sisters explains the processes of transcription and translation, which are essential 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 tRNA brings amino acids to form a polypeptide chain, resulting in protein formation.

Which of the following processes occurs first in protein synthesis?

• Translation

• Replication

• Transcription

• Mutation

In eukaryotic cells, where does transcription take place?

• Mitochondria

• Nucleus

• Ribosome

• Cytoplasm

What is the role of RNA polymerase during transcription?

• It translates mRNA into proteins.

• It uses a DNA template to create mRNA.

• It transports amino acids to the ribosome.

• It synthesizes DNA from RNA.

Where does translation occur in the cell?

• Golgi apparatus

• Endoplasmic reticulum

• Ribosome

• Nucleus

What determines the sequence of amino acids during translation?

• The sequence of DNA

• The sequence of rRNA

• The sequence of mRNA

• The sequence of tRNA
