Worksheet Students will examine crime scene evidence to determine who is responsible for eating the Queen's special imported Lindbergher Cheese. Students will model the process of electrophoresis and DNA fingerprinting. Worksheet Students answer multiple choice questions on science ethics relating to genetics cloning, gene therapy. The class then discusses the pros and cons of each of the questions.In this activity, students will examine the epidermal ridge patterns of their fingers using a microscope.
They will identify if they have loops, arches or whorls, construct a graph of their class data, and analyze the class data. They will also learn how random events that occur during embryological development can influence their phenotype as adults. Friction ridges are raised portions of epidermis outer layer of skin cells found on the fingers, toes, palms and soles. It is thought that these ridges help in gripping and in providing a finer sense of touch.
They do this at least in part by amplifying vibrations caused when fingers rub against an uneven surface. Ridge patterns are not a purely heritable trait. Identical twins, who have identical DNAdo not have identical fingerprints, though they are often very similar. Some phenotypes, like human blood type e. Other phenotypes have less heritability. Ridge patterns are believed to result from a combination of these three factors, with random developmental events playing a significant role.
Of the three influences on phenotype, random developmental events are probably the most challenging to explain to students. As a multicellular organism grows and develops, cells divide mitotically to produce clones. However, as cells migrate during development, they may be exposed to slightly different environmental influences, causing their phenotype at maturity to differ from their sister cells, even when they have identical DNA.
Many students will already be familiar with the concept of cellular migration, having heard that the surface layer of their epidermis is continually sloughed off and replaced by fresh cells that have migrated toward the surface of the skin from lower layers see diagram below. Early in embryological development weeks after fertilizationthe embryonic skin is made up of a single layer of ectoderm cells above a layer of mesenchyme tissue.Minecraft glfw error 65539 invalid key 4
As the ectoderm cells divide, they form layers, with new cells migrating from the ectoderm to these various layers. By the eighth week of development, the epidermis is three to four cell layers thick. At around 6. The volar pads, which derive from the mesenchyme tissue and appear like bumps on the palm, influence the ridge patterns that will start to develop at around 10 weeks post-fertilization.
After around 24 weeks, the fetus has the same epidermal ridge patterns it will possess for the rest of its life. Some of the random developmental events that are believed to influence how the ridges form include differential stresses or pressures on various parts of the skin; differential shapes of the volar pads prior to ridge formation; differential timing of ridge formation e.
Heritability is a measure of how much of the variability of a trait within a given population is thought to be due to genetic influences i. As such, the concept can be instructive in conveying the idea that DNA is not destiny. For example, two tall parents could have a short child either because they were both heterozygous for height or because their child did not get sufficient calcium or protein in its diet. Determining heritability can be challenging, particularly for behavioral phenotypes or for traits in which no specific genes have been identified.
Determining the heritability of intelligence, for example, is problematic not only because there are no known genes or DNA sequences for intelligence that can be measured, but also because it is not entirely clear what intelligence is or how it should be measured. To further complicate matters, the classic heritability studies using twins have a slight bias due to the fact that twins often share a social environment even when separated at birth, drawing into question whether a behavioral similarity was due to a genetic influence or a common environment.
Consequently, different investigators, using a variety of different methodologies, have calculated a range of different heritabilities for traits like intelligence, neuroticism and addiction.Jump to navigation. Hundreds of teachers have brought engaging hands-on biotechnology activities to their classroom through professional development workshops, classroom visits and material and equipment loans. Due to budget cuts, materials cost is now associated with the activities.

How is the effect of an antibiotic different for different species of bacteria? This activity touches on the history of early antibiotics research as well as serves as an example of how observation leads to discovery. We have optimized a set of experiments to fit the high school classroom working with an antibiotic producing fungus and species of bacteria to emulate early observations of antibiotic effect on bacteria.
Students normalize cultures of Penicillium fungi green bread mold as well as bacterial species Staphylococcus epidermidis, Microcuccus luteus, and Enterobacter aerogenes using spectrophotometry before co-culturing the fungus with the bacteria to witness the antibiotic effect.
Students then measure the results of co-cultivation by quantifying the optical density of the bacteria at the end of one week of experimentation. How do you purify DNA from cells?
This activity provides a first-hand understanding of how DNA can be isolated for further analysis, such as DNA fingerprinting. Students also reinforce their understanding of cell structure and biological macromolecules. We use a kiwifruit protocol because it uses commonplace materials and requires little equipment.
What is electrophoresis? Students use agarose gel electrophoresis to determine the composition of different biological materials. This activity helps students learn how molecules can be separated and identified by electrophoresis.
How is DNA evidence prepared and analyzed in a crime case? Students perform agarose gel electrophoresis to analyze DNA samples from a mock crime scene. Based on DNA fingerprinting profiles that are simulated to represent the three suspects, and DNA from the crime scene, students determine which suspect likely committed the crime.

This activity helps students understand how DNA variation in individuals can be analyzed in practical applications such as genetic testing and forensics. This activity will allow students to evaluate two patients with possible neurological symptoms.Teachers Pay Teachers is an online marketplace where teachers buy and sell original educational materials.
