In which application do principles of genetics provide cells with mRNA to manufacture specific proteins?

• A. Gene Cloning
• B. mRNA Vaccines
• C. Protein Synthesis
• D. Genetic Sequencing

Answer: (B)

In the context of mRNA vaccines, principles of genetics play a crucial role by providing cells with the instructions necessary to produce specific proteins, particularly antigens that stimulate an immune response. The mRNA in these vaccines contains the genetic code derived from a pathogen, such as a virus. When this mRNA is introduced into the body through vaccination, it is taken up by host cells, which then use the cellular machinery to translate the mRNA sequence into a corresponding protein. This process effectively imitates a natural infection without causing disease, allowing the immune system to recognize and respond to the protein. By stimulating the production of specific proteins identified in the pathogen, the immune system can develop a memory of these proteins. Thus, if the individual is later exposed to the actual pathogen, their immune system can recognize and respond more effectively. In contrast, gene cloning, protein synthesis, and genetic sequencing focus on different aspects of genetic manipulation or molecular biology. Gene cloning is about creating copies of specific genes, protein synthesis refers broadly to the process of translating mRNA into proteins, and genetic sequencing involves determining the exact order of nucleotides in a DNA or RNA molecule, which does not directly involve the production of proteins via mRNA.
