DNA Testing and the Conviction of Criminals

There have been many incidents where cases have needed a solid prosecution in order to convict the defendant in a murder or rape case. This is where DNA Testing comes in to help. By taking a DNA test, a person can be found guilty or not guilty. If a person claims they have been raped there can be a sperm sample taken from the suspect in order to prove that he is guilty or not. In addition, in a murder case there can be blood taken from the suspect so they can tell of his innocence. There are several ways to determine whether a person is guilty or not by this method. Many cases have begun to use this method saying that it is foolproof. People say this is the method of the future of crime…show more content…

So you ask, "How does this work to catch or release criminals?" DNA is very simple and small. Everyone has different patterns. Using certain machinery to detect a person's DNA solves these patterns. This evidence will create a future in crime scene investigation.

At the University of Texas in Austin, there is a DNA facility, which maps DNA. They have several machines that are used to detect DNA. One of these machines is the ABI Prism 3700, which is a DNA analyzer that can analyze up to ninety-six samples of DNA. This can then run for twenty-fours without being attended to for operation (Harkey, 2002).

Another machine that is used is the Molecular Dynamics Fluorimager FSI. This device is a quantitative gel and blot system in order for scientists to read. This labels the DNA and proteins on micro plates. A laser scans the DNA a then provides an image for studying the DNA (Harkey, 2002).

In Time Magazine an article states On February 28 1953, James Watson and Francis Crick broke the DNA code and discovered that the DNA strand is double helix and forms like a ladder. They found that cytosine and guanine were paired together and that adenine and thymine were paired. They discovered the building block of life (Wright, 1999). DNA is found in all living organisms.

Now that I have given some of the background information on the DNA strand, I want to explain what is done to catch the criminals of murders and rapes. Since, a person's DNA cannot be found in any

1 As they were speaking to the people, the priests and the captain of the temple guard and the Sadducees came up to them,

2 being greatly disturbed because they were teaching the people and proclaiming in Jesus the resurrection from the dead.

3 And they laid hands on them and put them in jail until the next day, for it was already evening.

4 But many of those who had heard the message believed; and the number of the men came to be about five thousand.

5 On the next day, their rulers and elders and scribes were gathered together in Jerusalem;

6 and Annas the high priest was there, and Caiaphas and John and Alexander, and all who were of high-priestly descent.

7 When they had placed them in the center, they began to inquire, By what power, or in what name, have you done this?"

8 Then Peter, filled with the Holy Spirit, said to them, Rulers and elders of the people,

9 if we are on trial today for a benefit done to a sick man, as to how this man has been made well,

10 let it be known to all of you and to all the people of Israel, that by the name of Jesus Christ the Nazarene, whom you crucified, whom God raised from the dead--by this name this man stands here before you in good health.


12 And there is salvation in no one else; for there is no other name under heaven that has been given among men by which we must be saved."

13 Now as they observed the confidence of Peter and John and understood that they were uneducated and untrained men, they were amazed, and began to recognize them as having been with Jesus.

14 And seeing the man who had been healed standing with them, they had nothing to say in reply.

15 But when they had ordered them to leave the Council, they began to confer with one another,

16 saying, What shall we do with these men? For the fact that a noteworthy miracle has taken place through them is apparent to all who live in Jerusalem, and we cannot deny it.

17 But so that it will not spread any further among the people, let us warn them to speak no longer to any man in this name."

18 And when they had summoned them, they commanded them not to speak or teach at all in the name of Jesus.

19 But Peter and John answered and said to them, Whether it is right in the sight of God to give heed to you rather than to God, you be the judge;

20 for we cannot stop speaking about what we have seen and heard."
