Question
Chapter 11, Problem 18P
Summary Introduction
To determine:
The ways by which a prosecutor use DNA from the seed pods to build a case against the defendant.
Introduction:
DNA fingerprinting is defined as the method in which variable elements present in the sequence of DNA are isolated and identified. The DNA is obtained from a sample of cells such as skin, blood, or hair cells. They are a rich source of DNA.

The following gel shows the results of a crime scene investigation. Lane 1 shows a DNA sample
that was obtained from the scene of a crime (there was evidence of the criminal cutting himself, so
it's the criminal's blood sample that produced the DNA bands in lane 1).
Lanes 2-7 shows a DNA sample from six potential suspects held in connection with the crime.
Arrange the bands labeled A, B, C, D from largest to smallest.

The 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.
B) 300 bp, 400 bp, 100 bp, 600 bp
C) 600 bp, 450 bp, 300 bp, 100 bp
D) 400 bp, 300 bp, 600 bp, 100 bp
E) DNA fragment size can't be estimated using an agarose gel.

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.

- Please help me with this questionarrow_forwardSomeone broke into the bookstore and stole thousands of dollars’ worth of textbooks. Some hairs were left behind, from which DNA was extracted. An individual was caught with all five of the stolen textbooks in his bag. He claims his friend gave them to him. You decide to amplify two regions of the DNA (two loci, plural of locus) and digest the samples, and get the following result on the electrophoresis gel.L = Standard marker 1 = Suspect 1 2 = Suspect 2 3 = DNA from crime scene (Note: assume bands that are close in distance traveled are the same length. Higher concentrations of DNA can make a band appear to travel farther.)
