- 6. Multiple Choice
Which of the following describes the orientation of two amino acids when bonded?
carboxyl of first amino acid binds to carboxyl of second amino acid
amino of first amino acid binds to amino of second amino acid
carboxyl of first amino acid binds to amino of second amino acid

- 7. Multiple Choice
Which of the following describes the difference between bound and free ribosomes?
free ribosomes do not require ATP for dehydration reactions while bound ribosomes require ATP for dehydration reactions
free ribosomes synthesize proteins for the cytosol while bound ribosomes synthesize proteins for the membrane/secretion
free ribosomes are able to freely float between all parts of the cell while bound ribosomes are remain in the rough ER membrane
free ribosomes move between the nucleus to the cytosol while bound ribosomes remain in the cytosol
- 8. Multiple Choice
Which of the following describes the function of the tRNA?
tRNA has the codon required for translation
tRNA allows for the translocation step
tRNA has the RNA transcript for protein synthesis
tRNA brings the amino acid to the ribosome
- 9. Multiple Choice
Which of the following describes the function of the mRNA?
mRNA moves the ribosome to the appropriate location in the cell for synthesis
mRNA has the anticodon to pair with tRNA for protein synthesis
mRNA is responsible for being the transcript synthesized from the DNA
mRNA will make more copies of itself to enhance the process of transcription
- 10. Multiple Choice
