Answer: GCT AGA
Explanation:
The complementary binding of the nitrogenous bases takes place in the process of DNA replication.The complementary mRNA strand is GCT AGA. The whole process of DNA replication consists of two steps: Transcription and translation.
The transcription can be defined as the process by which the DNA is converted into mRNA and then the information for the protein synthesis is carried by the mRNA.
The mRNA undergoes the process of splicing to produce the desired protein. This step is known as translation.
