ADVANCED MOLECULAR MODEL
OF DNA AND ITS REPLICATION
Kit #71-A
This advanced modeling kit explains DNA’s double helix
model in greater detail, and emphasizes construction of the
nucleotides (the phosphate group, deoxyribose sugar, and
one of four bases) . While replication is observed, protein
synthesis, transcription, and translation are not illustrated .
Twelve, nine-rung models can be constructed with each kit .
Accommodates unlimited classes, each with 12 groups of two students.
Kit No. 71-A $115.45

NATURAL SELECTION: VARIATION
IN SPECIES AND NORMAL
DISTRIBUTION
Kit #74R

Variation in species and normal distribution are brought to life with
this kit. Students use our exclusive Variation Profile Tubes to sort
a variety of physical characteristics in sunflower seeds. They gain
experience in constructing visual graphs, histograms, and linear
graphs from data collected by the entire class . The idea that greater
validity of information gathered from a large sample versus a smaller
sample is illustrated beautifully by comparing class results in the
Variation Profile Tubes to the student’s own histograms and graphs.
Accommodates unlimited classes, each with 30 groups of one student.

DNA FINGERPRINTING DIAGNOSTICS
(REPLICATION, PCR AND RFLP)

Kit #75
This timely kit introduces biotechnology, forensic science,
or AP Biology students to the concepts of DNA replication
and how it relates to PCR (Polymerase Chain Reaction) and
RFLP (Restriction Fragment Length Polymorphism) analysis
of DNA . They also observe how DNA analysis can be used to
diagnose disease .
This activity is a great introduction or review if you are
fortunate enough to have the equipment and materials to do
gel electrophoresis and DNA fingerprinting.
Accommodates 10 groups of three students.
