Answer Details
An accurate identification of a rapist can be carried out by conducting a DNA analysis.
DNA analysis involves comparing the DNA of the suspect with the DNA evidence collected at the crime scene, such as semen or saliva. If the DNA profiles match, it provides strong evidence that the suspect was present at the crime scene and could be the perpetrator of the crime. DNA is unique to each individual, except in the case of identical twins, making it a highly reliable method for identifying suspects.
On the other hand, RNA analysis is not typically used for forensic identification because RNA is not as stable as DNA and is more difficult to isolate and analyze. Blood group typing can provide some limited information, but it is not as reliable as DNA analysis since many people can share the same blood group. Behavioural traits tests, such as polygraph tests, are also not reliable for forensic identification since they are not accurate enough to provide definitive evidence of guilt or innocence.
