INDIVIDUAL DNA AND NUCLEIC ACID MODELING

Kit #71-513

This kit allows a student to construct a model of an 8-rung ladder segment of a DNA molecule
and then build a molecular model of the basic components of the nucleotides of RNA and
DNA . This kit combines the features of the Molecular Model of DNA and Its Replication
(Kit #71) and Nucleic Acid Molecular Structure (Kit #513) for an individual student . All the
components are reusable and the nucleotides (when using more than one kit) can be linked
together to form a DNA model .
Accommodates unlimited classes, each with 1 group of students.
Kit No. 71-513 $27.70

HUMAN GENETICS EXPERIMENT
Kit #7
An excellent activity to introduce students to Mendelian genetics!
The experiment is based on the transmission of a single inherited
trait - the ability to taste harmless PTC (phenylthiocarbamide) .
The goal is for students to determine if they have this gene . They
first collect data by testing family members for this trait. Next,
they correlate and pool the PTC data for the entire class . Finally,
the students calculate the random segregation data according
to the Hardy-Weinberg Law . Background information about the
Hardy-Weinberg Law is provided in a supplementary section . It
also includes information about calculating gene frequency and
the genetics of ABO blood typing .
Accommodates two classes, each with 25 students.
Kit No. 7 $30.45
