Solution

The components of the in vitro transcription mixture for the production of mRNA are:

  1. Ribonucleotides: These are the building blocks of RNA. They are necessary for the synthesis of the RNA strand.

  2. RNA polymerase: This is the enzyme that synthesizes the RNA strand from the DNA template.

  3. DNA construct: This is the DNA template from which the RNA is synthesized. It contains the sequence of the gene of interest.

The other components listed (RNA inhibitor, Wheat germ extract, Primer(s), RNase) are not typically part of an in vitro transcription mixture for the production of mRNA.

RNA inhibitor and RNase would actually be detrimental to the process as they would inhibit the synthesis of RNA and degrade RNA, respectively.

Wheat germ extract is used in in vitro translation (protein synthesis), not transcription.

Primers are used in processes like PCR and DNA sequencing, but not typically in in vitro transcription.
