Ans.
During protein synthesis, genetic information gets transferred to mRNA from DNA as codons. Each codon or genetic code is made up of three nucleotide bases and codes for a specific amino acid during translation. The genetic code for proline is CCU, for aspartate is GAC, for glycine is GGU, and for lysine is AAA.
Thus, the mRNA codons that can code for a protein with given sequence is CCU-GAC-GGU-AAA.
However, the sequence may change these amino acids also can be coded by other codons because there are more than one codon for many amino acids).
Answer:
mRNA codons: CCU-GAU-GGU-AAA
Explanation:
Pro - Asp - Gly - Lys
Genetic code for proline are: CCU/CCC/CCA/CCG
Similarly, genetic codes for Asp are GAU/GAC
Genetic code for Gly: GGU/GGC/GGA/GGG
Genetic code for Lys: AAA/AAG
A mRNA having one codon for each of these amino acid could code for the given protein sequence. So, a mRNA with following sequence can code for protein with amino acid composition "Pro - Asp - Gly - Lys ":
mRNA codons: CCU-GAU-GGU-AAA
