I followed Nicky Verstappen’s case closely and was very curious about how DNA research
works exactly. So, I will tell more about DNA research in my presentation.
1. What is DNA?
DNA is a package of all your hereditary characteristics, these are all the things your parents
passed on. These packages are made up of separated smaller pieces of DNA, called genes.
Each gene contains information about the specific formation of protein. These pass your
hereditary characteristics along, like the colour of your eyes and the colour of your hair.
The steps of the stair form the four(4) nucleobases ACGT. These steps form a code. This code
is readable by its letters. Depending on the order in which the bases are found in the spiral
staircase, this will form a unique DNA code.
In cases of four(4) years or more in prison, the suspect is obliged tot give up DNA. This
happens in prison or at the police station. Usually by means of a cotton swab along your
cheek. It is also possible through a prick in your finger.
2. What is DNA research?
At the crime scene, this is the place were the crime was committed. A detective team goes
searching for DNA material, such as hair, blood, skin flakes and fingerprints. Think of a
mouth mask, a piece of clothing, the rim of a used glass or a cigarette but.
When they have found traces, it will be sent to the Dutch Forensic Institute. There the DNA
material will be examined.
So, how does this work?
The researchers start isolating the DNA from the traces. Then they have to multiply these
DNA molecules.
When the researchers have enough DNA, they can create a DNA profile. They do this by
looking at the DNA characteristics in ten(10) different areas on the DNA. They pas this
information on again the previously mentioned codes.
They will look for a ‘match’ on the basis of the DNA profile found at the crime scene
For example,
Suppose the police found a trail of blood on the window during a burglary. They also arrest a
suspect. A DNA profile is drawn up for both. A comparison of these two DNA profiles can
yield two results. The DNA profiles will be different of or will be the same;
works exactly. So, I will tell more about DNA research in my presentation.
