An accurate identification of a rapist can be carried out by conducting a DNA analysis.
A rapist may have left behind substances like blood or spermatozoa with which his identity will be determined by way of DNA analysis.
Now to the right option…
- Option A is incorrect; RNA analysis will not show in details the genetic code and sequencing that will appropriately identify the criminal.
