This system highlights the diversity of strategies while reinforcing the DNA/RNA divide. When a virus infects a cell, it often produces RNA transcripts of its genome to create proteins, but these mRNAs are copies, not the original genomic material co-existing with DNA within the virion.
Lifecycle Dynamics: How Viruses Navigate DNA and RNA Roles
The choice between DNA and RNA is not arbitrary; it reflects a trade-off between stability and mutability. Most organisms follow this path, but viruses have evolved numerous shortcuts and detours.
The Functional Implications of Genetic Choice To address whether a virus can possess both nucleic acids, it is helpful to revisit the central dogma of molecular biology: DNA makes RNA, and RNA makes protein. This system highlights the diversity of strategies while reinforcing the DNA/RNA divide.
Lifecycle Dynamics: How Viruses Navigate DNA and RNA Roles
Conversely, bacteriophages like T4 use DNA as their genome, which is transcribed into RNA to produce new viral components. No known virion packages both a DNA genome and an RNA genome within the same protein shell, as this would create an inefficient and redundant system for infection.
