DNA is present in every single cell in our bodies

The DNA is in our saliva, and even in our blood. The DNA that we have in our body identifies us. These people can easily use a process called DNA fingerprinting to identify who we are by using small pieces of evidence for example, DNA or saliva. For example, if you had a girl and it was not yours they can test if that baby girl has your DNA and if it does not match your DNA you will give the baby back and go to jail that is why DNA fingerprinting is so important but it is a much harder process to do . It also is useful during crime scenes. How they perform the process is the lab takes your allele profile and they get the evidence sample and the suspect sample. Then what they do is they figure out if those STR alleles do not match then he did not do the act. If his alleles are true what they would do is they would look at the population.
DNA identification also has another repeat that the scientists investigated noncoding DNA but they have found a short one and it is called short tandem repeat analysis. This process allows you to use DNA and differentiate between two people and it is hard because most of everyone’s DNA is the same. It can easily be compared with two individuals. What an STR is made up of is, it is made up of three to four short nucleotides; these nucleotides which make up the back part of the DNA helps the amino acids in proteins match them at specific sequences. For example, if the protein did not function well or sequence well with the amino acids the protein would not function. Non working proteins are bad for the human because this leads to diseases in the body. These precise sequences of DNA help us understand different individuals' DNA.
Sequences of DNA are repeated numerous times; it is called Short Term Repeat analysis. If they wanted to find a useful part of their DNA they would have to find it at one tenth of one percent. Because this end does not really code for anything, so therefore they are able to recognize and differentiate their DNA much easier. In order for them to apply STR to human identification, the FBI had to take multiple samples of different people. They analyzed the DNA samples by the STR sizes, even ruptured DNA was able to be analyzed and checked. After the DNA was analyzed they would have it go through the database, it would not be solved in an hour it took them a long time.
The Technology that we have makes us distinguish between an individual and multiple individuals. And to protect innocent people who did not do the crime. In addition to STR and DNA fingerprinting a match does not consider that they are completely guilty. The DNA databases would make it into a more simple task by connecting with past offenders of those who did a recent crime. For example, if someone did a recent act of murder his DNA samples would still be in the DNA database so he would be guilty again because all of the information is stored in that specific database, that is why if someone commits a crime they would be caught immediantly or in the next few days.
In conclusion, DNA is one of the most interesting factors in our lives. One little bit of DNA helps police officers and other enforcers track us to where we went and what we do. These STR regions are found on nuclear DNA and are then activated with specific primers using the polymerase chain reaction. The DNA pieces are then separated by a process called electrophoresis. The process of electrophoresis also lets you know how many repeated STR sequences still exist. STR measures the repeating blocks or subunits, it compares your DNA to someone else's using samples. Finally, when they are ready they ship the crime scene analysis they send it to a DNA laboratory. They would examine it to find fluid body stains that might consist of DNA. then DNA is taken out with a swab. The process of amplification allows them to analyze easy DNA samples. After the process of amplification the DNA enters a machine which separates all of the DNA fragments. You make allele calls, then after you return the evidence to the person. Then the person finds out by the computer because certain injections are placed in there and they know if the person did it by the lasers on the computer. They are then to figure out who is the guilty one. Then your case is confirmed and then you are happy. As you can see from this report, the process of STR is so interesting and so is DNA fingerprinting. I accidentally found a platform called Homeworkfor.me. I was surprised to see so many sociology research topics for college students. Everyone can have a look at them absolutely free.
