Product Details

General, Organic and Biological Chemistry Explore the procedures used in the chemical testing of nucleic acids! Nucleic acids—RNA and DNA— are essential macromolecules involved in the storage, transfer and expression of genetic information. Students will marvel at their ability to extract nuclear material from fruit and determine its composition using simple chemical tests. From there, students analyze the isolated nucleic acid macromolecule to verify the composition of the phosphate, deoxyribose and nucleotide groups. Complete for 24 students working in pairs.

Performance Expectations

MS-PS1-1. Develop models to describe the atomic composition of simple molecules and extended structures.
MS-PS1-2. Analyze and interpret data on the properties of substances before and after the substances interact to determine if a chemical reaction has occurred.
HS-PS1-1. Use the periodic table as a model to predict the relative properties of elements based on the patterns of electrons in the outermost energy level of atoms.
HS-PS1-2. Construct and revise an explanation for the outcome of a simple chemical reaction based on the outermost electron states of atoms, trends in the periodic table, and knowledge of the patterns of chemical properties.
