Q 28E - Organic Chemistry (Mcmurry)

Question

Question: What anticodon sequences of tRNAs are coded for by the codons are :

1. AAU
2. GAG
3. UCC
4. CAU

Step-by-Step Solution

Answer

1. The codon AAU codes for aspartic acid, and the anticodon is UUA.
2. The codon GAG codes for glutamic acid, and the anticodon is CUC.
3. The codon UCC codes for serine, and the anticodon is AGG.
4. The codon CAU codes for histidine and the anticodon is GUA.

Step 1: Definition of anticodon sequence

A sequence of three nucleotides on a tRNA molecule that bond to a complementary sequence on an mRNA molecule is defined as an anticodon sequence

Step 2: Explanations

1. The codon AAU codes for aspartic acid, and the anticodon is UUA.
2. The codon GAG codes for glutamic acid, and the anticodon is CUC.
3. The codon UCC codes for serine, and the anticodon is AGG.
4. The codon CAU codes for histidine and the anticodon is GUA.
