Textbook Question
Chapter 14.3, Problem 1CSC
Guilty or Innocent?
When biological evidence was found in one of the Haynesworth case files in 2009, the sample was 25 years old. Fortunately DNA doesn't degrade very fast.

Question: How can DNA evidence be used to convict or exonerate a defendant? Why is DNA evidence so powerful?
Answer:
DNA evidence can be used to perform DNA profiling to determine the genotype of the specific DNA sample. With just a small amount of DNA, PCR can produce billions of copies of that specific segment. The segments that are used are from non-coding regions that contain STR’s or short tandem repeats. These very short DNA sequences are repeated and are specific to individuals because we inherit them from our mother and father. Gel electrophoresis separates the PCR products based on their size and each band is compared to the allele ladder. This process helps to identify the alleles present in the original samples. DNA profiling is performed at many loci to be able to tell the genetic difference between different individuals with a lot of certainty. The DNA from the different suspects is compared to the allele…

how it is accomplished. b. The following mother wanted to confirm to her
husband that the two children were actually his genetic children. She decided
to have a paternity test done. The test was performed by first collecting cheek
cell samples from each children, the mother and the father in question. The

Explain.arrow_forwardYou are a forensic scientist in charge of DNA samples in a case where a man was murdered. You conduct gel electrophoresis on the samples to determine the DNA profile of the samples. The rows of bands have been marked to make it easier to reference the bands. The sample marked 'evidence' came from under the victim's fingernails, likely indicating a struggle. There are two suspects in the case, both of whom are brothers, they are marked suspect 1 and suspect 2, for brother 1 and brother 2, respectfully. Does the evidence collected match the DNA profiles of either brother? If yes, which one? If no, then would it be likely that the actual criminal is a family member of the brothers? If yes, what could the relation be (mom, dad, cousin, aunt, or uncle)? Note: there is a sister in their family, their parents are both still alive, and they have a robust extended family. The brothers are not twins.arrow_forward

- Directions: The following story is about a crime solved through biotechnological techniques. 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.
