Why are entire genomes not used for DNA profiling?
Why are entire genomes not used for DNA profiling? The genome analysis either by DNA profiling or DNA sequencing for forensic purposes would require high amount of economy and time due to “more sequence unidentity” any two people.
How long does DNA last?
Last year, researchers estimated that the half-life of DNA — the point at which half the bonds in a DNA molecule backbone would be broken — is 521 years. That means that, under ideal conditions, DNA would last about 6.8 million years, after which all the bonds would be broken.
