Forensic Biology unit 2 discussion board 2

The Discussion Board (DB) is part of the core of online learning. Classroom discussion in an online environment requires the active participation of students and the instructor to create robust interaction and dialogue. Every student is expected to create an original response to the open-ended DB question as well as engage in dialogue by responding to posts created by others throughout the week. At the end of each unit, DB participation will be assessed based on both level of engagement and the quality of the contribution to the discussion.

At a minimum, each student will be expected to post an original and thoughtful response to the DB question and contribute to the weekly dialogue by responding to at least two other posts from students. The first contribution must be posted before midnight (Central Time) on Wednesday of each week. Two additional responses are required after Wednesday of each week. Students are highly encouraged to engage on the Discussion Board early and often, as that is the primary way the university tracks class attendance and participation.

The purpose of the Discussion Board is to allow students to learn through sharing ideas and experiences as they relate to course content and the DB question. Because it is not possible to engage in two-way dialogue after a conversation has ended, no posts to the DB will be accepted after the end of each unit.

Assignment Guidelines

The bones of the face, or skull as it is sometimes referred to, are there for the purpose of protecting and supporting the entrance to the digestive system and the respiratory system. These bones also provide sites for the attachment of muscles that control the mouth, eyes, scalp, and lower jaw. The bones and muscles of the face and head are all needed by forensics teams to recreate what was once the face of an individual. This is known as facial reconstruction. The skull provides clues to the personal appearance. Facial reconstruction can put a name on an unidentified body in a modern forensic case.

• In 4–6 paragraphs, address the following:
  • Why do you think facial reconstruction is important to a crime scene? Explain.
  • What do you think are the most significant challenges associated with facial reconstruction? Explain.
  • What is the most important historical contribution to the study of facial reconstruction? Why?
  • What role do you think technology has played in improving facial reconstruction techniques? Provide an example to support your argument.
• Post a new topic to the Discussion Board that contains your responses to the above questions.
• Comment on at least 2 other students’ posts.

Pin ItAs you study DNA, you find that every person’s DNA is different from another’s. Identical twins are the only people whose DNA is the same. Consider your parents and your siblings. Even though your brother and your sister have the same parents, it is unlikely that you look exactly like them unless you are identical twins. You may have common features, and you will all share common DNA among yourselves, but only identical twins will have the exact same DNA. DNA testing is used for many reasons such as the following:
Identify potential suspects whose DNA may match evidence left at crime scenes
Exonerate persons wrongly accused
Match organ donors
Assignment Guidelines
Address the following in 4–5 pages:
In your first case, you have been asked to list and explain the steps that you would use to identify and analyze DNA from a person who has been in prison for 10 years. The results of your test may exonerate the person.
Once the physical evidence has been delivered to the forensics lab, what is the process of identifying DNA? Be specific, and explain in detail.
Consider that the evidence is over 10-years old.
Once the DNA evidence has been identified, what is the process of analyzing the DNA? Be specific, and explain in detail.
What challenges exist that can make your analysis inadmissible in court? Explain.
How are tissue matches made? Explain.
Why is it important to utilize different DNA testing methods? Explain.
Why is it that some methods may be preferred over others? Explain.
Other than forensic uses, DNA testing is essential in paternity testing.
What are the steps used to carry out a paternity test? Explain in detail.
Why might the results of a paternity test be significant in a court case? Explain.
