How is STR used in forensics science?
Short Tandem Repeats (STRs) are repetitive sequences of DNA that vary in length among individuals, making them valuable for forensic science. They are commonly used in DNA profiling to identify and compare genetic material found at crime scenes, such as blood, hair, or skin cells. STR analysis allows forensic scientists to generate unique DNA profiles, which can be matched to suspects or victims, aiding in criminal investigations and paternity testing. The high degree of variability and the ability to analyze multiple STR loci simultaneously enhance the discrimination power of DNA evidence.
How do you store blood evidence?
You typically want to collect wet blood with a cotton swab and allow the swab to dry completely before placing it inside a non airtight container. (Most cotton swabs in a CSI's kit will have a small hole in which to place the swab for drying, and will also double as a carrying case). For blood that has already dried, you can scrape a sample into a pharmecutical fold or into coin collector's envelope (a small 1 inch by 1 inch manilla envelope). The point is to allow the sample to dry and breathe so that mold does not grow on the sample, thereby destroying the sample. The point of ALL evidence collection and preservation techniques is so that when the case goes to trial in about 9 years, every piece of evidence presented is exactly the same as when it was collected.

Why is it important not to contaminate a crime scene?
The answer is in your question: contamination. To contaminate something is to adulterate it, to ruin it. In this case, it is the evidence that is ruined. Contaminating a crime scene is essentially making a difficult job performed by an often less than qualified group of people far more difficult than it should be or needs to be. It seriously reduces the potential to secure a conviction of whomever committed the crime at that scene.
That, and you could be criminally charged with a variety of misdemeanor and/or felony complaints.

How does forensic science collect evidence?
They dust for finger prints and compare them to police records. They look for any data residue, for example hair strands, eye lashes, blood or skin and do DNA tests.
Answer:
Evidence is any material, residue, or other trace that can identify the cause or perpetrator off a crime. The forensic investigator:
- avoids contaminating the scene with his presence
- gathers evidence which may be related to the crime in a manner that its original location is known and it is not contaminated by the gathering process
- maintains the evidence through a chain of custody to prevent tampering with the evidence
- examines the evidence in an established method using appropriate procedures and tests
- writes a report on the evidence which includes the results of the examination and any inference that the investigator may make of the data
