11ea8d43_abb3_4821_b445_c3bd17e32528_TB6697_11_TB6697_11 -alanine is a dipeptide containing alanine and another amino acid linked together by a peptide bond. The compound that generates alanine is the one that provides the corresponding tRNA with the correct anticodon sequence for alanine. The anticodon for alanine is 5'-GCA-3'. This sequence pairs with the codon 5'-TGC-3'. Among the four compounds, only dCMP has a pyrimidine base (cytosine) in the third position of the codon, which matches the corresponding pyrimidine base (uracil) in the third position of the anticodon for alanine. Therefore, dCMP is the best choice to generate 11ea8d43_abb3_4821_b445_c3bd17e32528_TB6697_11_TB6697_11 -alanine.
