Can you please check if these sentences are OK? Thank you.

1)Forensic science adopts different scientific methods to catch criminals.
2)In particular, scientists can examine a suspect’s fingerprints or check blood type.
3) They can also check teeth and look at dental records to identify victims.
4) In addition, they can take x-rays to find out about medical history.
5) The most accurate scientific technique is called DNA identification.
6)As every human has a different DNA, which unlike fingerprints can’t be changed, this technique has enabled scientists to convict thousands of victims as well as to investigate unsolved crimes.
