(b)
Interpretation:
The DNA code for the peptide,
Concept introduction:
The term DNA stands for deoxyribonucleic acid. Deoxyribonucleic acid is the most important biomolecule that stores genetic information of a living organism. In other words, DNA is the blueprint of all organisms. The DNA first synthesizes RNA by the process of transcription and then the RNA synthesizes the proteins by the process of translation.

Answer to Problem 27.20P
The DNA codes for
Explanation of Solution
In the case of DNA, thymine base is present instead of uracil base rest remains the same. The given peptide chain is shown below.
