Amoeba Sisters Protein Synthesis (Updated)

What is the role of DNA in determining traits such as eye color?

• It has no role in determining eye color.

• It codes for proteins that produce pigments.

• It provides pigments directly to the eyes.

• It changes pigments in the eyes over time.

Where does transcription occur within a cell?

• In the cytoplasm

• Within the ribosomes

• In the nucleus

• Outside the cell membrane

What is the function of mRNA in protein synthesis?

• It carries amino acids to the ribosome.

• It replicates DNA structures.

• It transfers messages from DNA to the ribosome.

• It forms the structure of ribosomes.

What is the significance of the mRNA editing mentioned in the video?

• It is critical for the mRNA to function correctly.

• It prevents the synthesis of proteins.

• It enhances the speed of transcription.

• It is necessary for correct protein folding.

What role does tRNA play in translation?

• It copies the DNA code directly.

• It carries amino acids to the ribosome.

• It consumes the mRNA after protein synthesis.

• It synthesizes new strands of DNA.

What is a codon?

• A special type of RNA polymerase

• A sequence of three nucleotides in mRNA

• A type of protein

• A transport mechanism in cells

How are amino acids brought to the ribosome?

• Directly from the nucleus

• Via tRNA

• By rRNA

• Through mRNA

Which amino acid does the codon AUG code for?

• Leucine

• Proline

• Methionine

• Lysine

What indicates the end of protein synthesis in the translation process?

• A peptide bond formation

• The ribosome disassembles

• A stop codon is reached

• All tRNAs leave the ribosome
