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.
  • Thus, the correct answer is option C.
