- Can you please check my answer and make sure it is correct. 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…a. DNA fingerprinting is a method of visualizing similarities and differences in the DNA sequence of individuals. Arrange the following items so that they show the DNA fingerprinting steps in proper order: - Gel electrophoresis - Stain or probe for DNA - cut DNA into fragments - Amplify DNA sample using PCR b. On the gel shown below are four DNA samples. Samples A to C are taken from tissues of landslide victims that are being identified, while sample D came from a hair sample brought by a mother looking for the remains of her son. (see img) i. If similar band patterns in a gel are created using the same restriction enzyme, what does that tell you about the DNA sequence of the samples? ii. In sample C, only two fragments were created. How many restriction sites (regions where enzymes cut) are present in sample C?Examine the gel from a Rape investigation below. If you were the DNA analyst you would conclude that: DNA size markers blood sexual assault evidence samples victim |suspect A suspect B female fracțion male fraction 1 2 3 4 5 6 A. Suspect B is excluded as the source of the evidence, but Suspect A cannot be excluded. B. Both Suspects A and B are excluded as the source of the evidence. C. Suspect A is excluded as the source of the evidence, but Suspect B cannot be excluded. D. Suspect B cannot be excluded as a source of the evidence. The results with Suspect A are inconclusive. E. Neither Suspect A or B can be excluded as a source of the evidence.

Why do you think the PCR method is of more use in crime scene investigations?questions below: Aura and Ryan are expecting a child. Aura has dark eyes and Ryan has light eyes. Aura's mother has light eyes. Draw a Punnett square and be sure to include the following information for full credit: 1. Place the parents alleles at the top and on the left side. 2. Write in the allele crosses inside the Punnett squares. 3. Write out the genotypes probabilities for an offspring. 4. Write out the phenotype probabilities for an offspring. 5. What is the probability that Aura and Ryan could have a child with light eyes, even if light is recessive to dark? Note: For this question, you will have to go further back into the family tree to get Aura's genotype.Please help me with the question below - it is based on genomics/developmental biology.
