Deoxyribonucleic acid (DNA) is a nucleic acid that contains the genetic instructions used in the development and functioning of all known living organisms and some viruses. The main role of DNA molecules is the long-term storage of information. DNA is often compared to a set of blueprints or a recipe, since it contains the instructions needed to construct other components of cells, such as proteins and RNA molecules. The DNA segments that carry this genetic information are called genes, but other DNA sequences have structural purposes, or are involved in regulating the use of this genetic information.
Within cells, DNA is organized into structures called chromosomes. These chromosomes are duplicated before cells divide, in a process called DNA replication. These compact structures guide the interactions between DNA and other proteins, helping control which parts of the DNA are transcribed.
[In a simple sentence] DNA is the building block of life. DNA is the genetic material for all living organisms and it contains information that is crucial for heredity. It determines your physical appearance and separates you from everyone else.
Forensic science uses techniques developed in DNA research to identify individuals and identify suspects who have committed crimes. DNA from semen, skin, or blood taken from a crime scene can be compared with the DNA of a victim or suspect, and the results can be used in court as evidence.

[Question] 10 years ago, when umno decided to charged Anwar Ibrahim under the sexual harassments, the authority took his hair, blood and skin sample's for DNA testing. I believe, since it was a high profile case, the authority were kept the record. So why can't the authority use the same DNA testing report to investigate saiful's allegation? Even if the report was done 20 years ago, DNA still will be the same and no changes on that……. why they want his blood sample again? Do they have any specific agenda? I'm wondering too, why they refuse to provide him or his lawyer, saiful's police report copy?
