Question

12. The above diagram is a representation of a tRNA base-pairing with an mRNA as it might be seen in the ribosome a. What is the name given to the sequence in the tRNA that base pairs with the codon in the mRNA? b. In the dashed triangle, is this end of the tRNA the 5' or 3' end? c. What is the predicted sequence of the mRNA sequence in the dashed square written 5' to 3'? d. What are these 3 nucleotides on the mRNA called? e. Which amino acid is attached to this tRNA, as represented by the dashed

Explanation / Answer

a. Anticodon arm pairs with the codon in the mRNA
b. 3'-end
c. 5'-AAG-3'
d. Triplet codon
e. AAG codes for Lysine.
