I'm currently watching the "Unnatural Selection" series on Netflix, which I find very exciting. Now I have a question about DNA, so it is always said that every person has a unique DNA. I would be interested in how you can imagine that. Are there any patterns such as The fingerprints?
DNA is a chain of base sequences that "create" proteins. These base sequences can have various changes and mutations and make up the individuality.
Example:
Paternity tests run in such a way that the tandem repeats (base sequences where the same is repeated several times "AGAGAG" eg) are searched for in the DNA. Two things play a role here: WHERE they appear in the DNA and HOW MANY there are. If there are several matches, one can conclude that there's a relationship, since mutations change very arbitrarily and quickly.
A database is created by sequencing the DNA and storing it on a computer.
