Show answer and explanation
Correct answer: (a) Messenger Ribonucleic Acid
Explanation
mRNA stands for Messenger Ribonucleic Acid, a single-stranded molecule transcribed from the DNA template.
It carries the genetic code that directs protein synthesis by specifying the sequence of amino acids.
mRNA vaccines (Pfizer-BioNTech, Moderna) instruct cells to make the spike protein of SARS-CoV-2 to trigger immunity.
