CHEM 120 Week 7 DQ 2 – Nucleic Acid Structure and Flow of Genetic Information (graded) In the news, we often hear examples of how DNA or the transfer of genetic information impacted someone’s life. Examples range from DNA fingerprinting to genetically engineered organisms to an individual with a genetic disease. In each of these scenarios, the structure of nucleic acids and the flow of genetic information through mRNA to protein are involved. Describe an example of the how the structure...

CHEM 120 Week # 3 DQ 1 – Chemical Reactions and Equations Understanding chemical reactions and the information that is available in a balanced chemical reaction is an important concept in chemistry.

CHEM-120 Week # 2 DQ 2 – Chemical Structures The electron configuration of an atom determines the number of electrons available to participate in bonding with another atom. One method of depicting the valence electrons that an atom has is through the Lewis structure. To begin this discussion, pick an element from the periodic table of elements. Identify the valence electrons and the orbitals in which they reside. You can use the textbook and lecture. Pick a peers post and answer each of ...

CHEM 120 Week 1 DQ 2 – Atoms and Atomic Structure There are a number of elements (minerals) that are important to human nutrition. These include sodium, potassium, calcium, chloride, magnesium, iron, copper, manganese, iodine, molybdenum, and selenium. There are many additional elements that are useful in industry. Using the periodic table of elements, pick one of these elements and determine the number of protons, neutrons, and electrons found in this atom. Be sure to check that you are n...

CHEM 120N Week 7 Discussion 1 - Carbohydrate, Lipid, & Protein Structures (graded) Carbohydrates, lipids, & proteins! Take a look around your home. Describe an example of a carbohydrate, lipid, &/or protein found in your home. Let’s see how many different examples can be described.

CHEM-120 Week 6 DQ 2 – Nuclear Chemistry and Energy (graded) Radiation can be found in different forms. Electromagnetic radiation is something that we use every day. Ionizing radiation can cause damage to living tissue. Take a look around you. Describe an example of a way in which you are impacted by radiation. Is this a type of ionizing radiation? What is the source of this radiation? Let’s see how many different examples can be identified.

CHEM 120 Week 6 DQ 1 – Polymers (graded) What do you have in your home that is constructed from a synthetic polymer? Identify the type of polymer and its monomer. List THREE examples each

CHEM-120 Week 4 DQ 2 – Acids and Bases (graded) While we often do not realize it, acidic & basic solutions are a part of our daily lives. Describe an example of when you have used an acidic or basic solution in your home. Let’s see how many different examples we can describe.
