Forensic Biology Discussion Board 3
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.
This unit specifically studies the molecule known as DNA, or deoxyribonucleic acid. DNA is the genetic material of all living organisms. DNA is a nucleic acid. Nucleic acids are a type of organic molecules that contain genetic material. DNA is found in the nucleus of every cell in the human body. Cells of living things are made of prokaryotic cells or eukaryotic cells. In prokaryotic cells, DNA is circular, and in eukaryotic cells, DNA is linear. The human body is made of eukaryotic cells, which is why your chromosomes are linear. The majority of the work involved in forensics is based on DNA. History discusses many people as having input into the discovery of DNA, but the most familiar names are James Watson and Francis Crick.
- In 4–6 paragraphs, address the following:
- What is the history of DNA?
- Out of all of the contributors to the field, who do you think has made the greatest contribution to the discovery of DNA? Why?
- In your own words, describe and explain the components and arrangement of DNA.
- In your own words, what is the process by which DNA replicates?
- In your own words, what is the relationship between DNA, genes, and chromosomes? Explain.
- What do you think is the most important use of DNA testing and analysis? Explain in detail.
