DNA in crime
Dna in crime is everywhere. It just happens to be how the dna is used. Dna can help investigators solve the crime. For example during a crime, as the killer or muderers kill someone, they might leave traces of their dna on the victim's body or somewhere around the crime scene.
Eventhough dna traces may help investigators solve a crime, dna may also give investigators wrong information. The killer or murderer may have cleaned up any trace of their own dna at the crime scene. The killer may have even put someone elses dna in the crime scene, so that the other person will look guilty, and the murderer will look innocent. The investigators might as well get the wrong idea as the saying says "Evidence doesn't lie." and blame the innocent person as being the killer.
Afterall, I think that dna is a very helpful tool towards solving a crime but sometimes can be a tricky tool to use. It may help you find the killer but on the other hand, accuse the wrong person. To be extra sure, I think that investigators should find dna or fingerprints on the murder weapon that is if they can find the weapon incase the dna belongs to another person before accusing the killer.
Everyone is unique based on their dna. Thats what make peoplw different from you and make yourself, well you! In a dna, their contains a dna structure. In the dna structure, their are nucleotides. In a nucleotide their are sugars, phosphate and a base. The only difference in nucleotides are the different bases. The four bases are adenine, thymine, guanine and cytosine. Each of the four bases are slightly different in shape.
