Solution
The correct option is C mRNA
The mRNA is the type of RNA which is synthesized from the DNA by the process of transcription. This mRNA contains the code of the gene on the DNA segment.
The mRNA codes for the proteins. In the experiments of proteomics, when there is a requirement to identify the proteins, a probe is synthesized.
The probe contains nucleotides and is synthesized with respect to the sequence of amino acids on the protein.
The probe can bind to the respective mRNA and help in the detection of the protein.
