The techniques used are DNA fingerprinting and polymerase chain reaction (PCR). DNA fingerprinting is a technique in which an individual’s DNA is analyzed to reveal the pattern of particular short nucleotide sequences. This pattern is claimed to be unique to the individual concerned and can thus be used for identification purposes. Polymerase chain reaction, on the other hand, is a technique used to replicate a DNA fragment so as to produce many copies of a particular DNA sequence. Why do you think there’s a need to generate several copies of the DNA? You will learn the answers to this as you go through the story. Read the story carefully and answer the questions that follow.arrow_forward

- Suppose a suspicious hair was found in a victim's home. A gel is set up with a DNA ladder in lane 1. The victim's DNA fragments are in lane 2, as a negative control. The DNA fragments of the suspicious hair are in lane 3. The DNA fragments of suspected criminal #1 are in lane 4, and the DNA fragments of suspected criminal # 2 are in lane 5. The resulting gel is below . Which suspect , if any, committed the crime? Explain your answer .arrow_forwardThe Evidence shows which suspect was at the crime scene? ( image of murder investigation) A) suspect A B) suspect B C) suspect C D) none were at the crime scene Which of the following choices most likely lists the sizes of the four DNA fragments in lane 6 ( second image) of this agarose gel stained with ethidium bromide? ( Note: the well that the DNA was loaded into is at the top of the gel image). A) 100 bp, 300 bp, 450 bp, 600 bp.
