16. 1) small subunit of the ribosome binds to mRNA
2) large subunit of ribosome binds to mRNA
3) A-site open
4) tRNA with anticodon UAC binds to mRNA codon AUG
17. "If a protein stays in the cytoplasm, it has to have a cytoplasmic sequence in the protein" -it is a true statement.
18. I think "transcription" & "translation" is the most important thing to learn.
19. Kinase enzyme helps to add the phosphate to the protein.
21. The place in the endomembrane system where protein can be degraded is lysozyme.
23. The anticodon is AGA, then the codon is UCU.
