● Stoichiometry is the use of quantitative relationships between substances that are involved in chemical reactions which determine the amounts of the reactants or the products (Bauer, Birk, & Mar ks, 2019). Stoichiometry - the process of determining the amounts of substances in a chemical reaction (Bauer, Birk, & Marks, 2019). ● It is used to relate the reactants and products by using calculations and balanced equations (Bauer, Birk, & Marks, 2019). ● By knowing the amount of a reactant o...

CHEM 120 Week 7 Discussion: Flow of Genetic Information - Protein Initial Post Instructions In the news, we often hear examples of how DNA or the transfer of genetic information impacted someone's l ife. 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. Using an example from the news or a scholarly ...
