Assuming that cells use the minimum possible number of tRNAs, how many tRNAs are there that carry tyrosine (tyr), and what are their anticodon sequences? Do the same for serine (ser). Explain how you know.
Given that there is just 1 for tyrosine: Anticodon= AUG
SER=UCU, UCC, UCA, UCG, AGU, AGC.
What is the correct anticodon sequences for serine? How do we know?
