- Python program that identifies a person based on their DNA by reading data from a CSV file.
- DNA has been used in criminal justice for decades. But how can forensic investigators identify to whom it belongs?
- Well, DNA is just a sequence of molecules. Each of them contains one of four different bases:
- adenine (A)
- cytosine (C)
- guanine (G)
- thymine (T)
- Humans have DNA arrange in ways that can repeat in unique short sequences called STR (Short Tandem Repeats).
- These repetitions can help us identify a person by its DNA.
- As exmaple, Alice has the STR
AGAT repeated four times in her DNA, while Bob has the same STR repeated five times.
- With this information, we can create a program that analyzes a sequence of DNA (from the sequences folder) a look for matches of other people DNA sequences (from database folder).
- It will read the information from a CSV table and process it accord
python dna.py databases/large.csv sequences/5.txt
- If we run
python dna.py databases/small.csv sequences/1.txt the program will output Bob.
- If we run
python dna.py databases/large.csv sequences/15.txt the program will output Sirius .
- If we run
python dna.py databases/small.csv sequences/3.txt the program will output No match since there are no matches with our database.
