After four to six days on average, symptoms of Ebola can begin. The period between the transmission of the virus and the start of symptoms is called the incubation period. For Ebola, the incubation period can be as short as 2 days or as long as 21 days.he period between the transmission of the virus and the start of symptoms is called the incubation period.

DNA profiling (also called DNA fingerprinting, DNA testing, or DNA typing) is a forensic technique used to identify individuals by characteristics of their DNA.lthough 99.9% of human DNA sequences are the same in every person, enough of the DNA is different that it is possible to distinguish one individual from another, unless they are monozygotic (identical) twins.
In little more than two decades, DNA profiling has become one of the most valuable tools in forensic science. By comparing highly variable regions of the genome in DNA from a sample with DNA from a crime scene, detectives can help prove the culprit's guilt--or establish innocence.Despite its utility in law enforcement, however, some applications of DNA have proven controversial.dvantages. The great advantage of DNA profiling lies in its specificity. Even relatively minute quantities of DNA at a crime scene can yield sufficient material for analysis. Forensic scientists typically compare at least 13 markers from the DNA in two samples.
