Q29-28E - Organic Chemistry (Mcmurry)

Question

Question: What anticodon sequences of tRNAs are coded for by the codons in Problem 28-26?

Step-by-Step Solution

Answer

In solution (a), the anticodon is UUA.

In solution (b), the anticodon is CUC.

In solution (c), the anticodon is AGG.

In solution (d), the anticodon is GUA.

Step 1: Introduction

Anticodons are three ribonucleotide sequences on tRNA that are complementary to mRNA codons.

Step 2: Explanation for (a).

The codon AAU codes for aspartic acid.

Thus,

The anticodon is UUA.

Step 3: Explanation for (b)

The codon GAG codes for glutamic acid.

Thus,

The anticodon is CUC.

Step 4: Explanation for (c)

The codon UCC codes for serine.

Thus,

The anticodon is AGG.

Step 5: Explanation for (d)

The codon CAU codes for serine.

Thus,

The anticodon is GUA.
