Question

look at the highlighted condons on the mrna. use the menus to select the proper base pairs and make the anticodons. 5 gaucuaaguaa aug cccg gaa uac uag ccu 3 done auc cua uac cuu

Explanation:

Step1: Recall base - pairing rules

In RNA, A pairs with U and G pairs with C. Anticodons are complementary to mRNA codons and are read in the 3' - 5' direction while mRNA is read 5' - 3'.

Step2: Analyze first highlighted codon

The first highlighted mRNA codon is AUG. Its complementary anticodon is UAC (since A - U and U - A, G - C).

Step3: Analyze second highlighted codon

The second highlighted mRNA codon is GAA. Its complementary anticodon is CUU (because G - C and A - U).

Step4: Analyze third highlighted codon

The third highlighted mRNA codon is UAG. Its complementary anticodon is AUC (as U - A, A - U, G - C).

Answer:

First box: UAC
Second box: CUU
Third box: AUC
