The antiparallel structure of DNA is important in DNA replication because it replicates the leading strand one way and the lagging strand the other way. During DNA replication the leading strand is replicated continuously whereas the lagging strand is replicated in segments known as Okazaki fragments.
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.
