Practice question
Question
During infection by single stranded RNA viruses, host immune system distinguishes viral RNA from the host RNA based on:
Explanation
In molecular biology, nucleic acid structure and recombination dictates that hairpin formation, Holliday junction resolution and translation control ensure fidelity. Therefore specific signals at the 5′ end of the RNAs is correct as it matches molecular mechanisms of gene expression, supported by mechanistic studies and conserved across related systems.
