Proteins are essential for all functions necessary for life in organisms. Proteins are created by reading the sequence of nucleotides in genetic material (DNA). During cellular processes known as transcription and translation, the DNA code is read, transferred into a copy called mRNA, and then the copy is read to create specific amino acids bonded together. The amino acids and their interactions create the specific shapes of proteins. In this activity you will be translating strands of DNA to mRNA, and then into small sequences of amino acids. The amino acids will then be bonded together based on their properties. The proteins will be analyzed for correct bonding patterns since the shape of the protein is directly related to the amino acid sequence and the protein's function.

DNA replication, mutations, the cell cycle, and cancer are often taught separately in high school biology. Composing an activity that connects the understanding of these concepts and how they are interrelated is not always done effectively. DNA replication is a normal task for all cells, yet some cells become cancer cells because of changes to their DNA. This unwanted mutation can surpass the check points in the cell cycle and overtake normal cells.

A full lesson plan on teaching Mendelian Genetics and how to use and understand Punnett squares.

Type: Lesson Plan

How is it that all cells in our body have the same genes, yet cells in different tissues express different genes? A basic notion in biology that most high school students fail to conceptualize is the fact that all cells in the animal or human body contain the same DNA, yet different cells in different tissues express, on the one hand, a set of common genes, and on the other, express another set of genes that vary depending on the type of tissue and the stage of development. In this video lesson, the student will be reminded that genes in a cell/tissue are expressed when certain conditions in the nucleus are met. Interestingly, the system utilized by the cell to ensure tissue specific gene expression is rather simple. Among other factors - all discussed fully in the lesson - the cells make use of a tiny scaffold known as the "Nuclear Matrix or Nucleo-Skeleton". This video lesson spans 20 minutes and provides 5 exercises for students to work out in groups and in consultation with their classroom teacher. The entire duration of the video demonstration and exercises should take about 45-50 minutes, or equivalent to one classroom session. There are no supplies needed for students' participation in the provided exercises. They will only need their notebooks and pens. However, the teacher may wish to emulate the demonstrations used in the video lesson by the presenter and in this case simple material can be used as those used in the video. These include play dough, pencils, rubber bands (to construct the nuclear matrix model), a tennis ball and 2-3 Meters worth of shoe laces. The students should be aware of basic information about DNA folding in the nucleus, DNA replication, gene transcription, translation and protein synthesis.

Type: Lesson Plan

This lesson focuses on: how cancer is caused by mutations that accumulate over time in cells' DNA, how the genes mutated in cancer are involved in normal cell growth & division, and how different types of mutations affect the functions of these genes. We recommend that this lesson be the first BLOSSOMS lesson on cancer, that the students use, from the series of three cancer lessons made by scientists at the Broad Institute of MIT & Harvard. It would be helpful if the students already knew basic information about DNA structure & function, and how mutations can affect the RNA & protein encoded by this DNA. Only paper and writing utensils, and the ability to print out or display the provided handouts, are necessary to complete this lesson. This lesson is intended to take one or two class periods. The two most central hands-on activities in the lesson are as follows:

• Students do an activity with a "mutation mat" (which is much like a bingo board) that shows how mutations accumulate in cells over time. This activity demonstrates why cancer is a disease of old age, because the more years that pass, the higher the chance that enough mutations have occurred in the relevant genes in a single cell, to cause it to become a cancer cell.
• Students complete a worksheet about various examples of "mutations" that could affect a steam engine train and cause it to barrel out of control (for example: if the train's brakes aren't working, or if the coal shovelers are shoveling too quickly).

The lesson ends with two additional discussion topics: how a person can be pre-disposed to cancer if he/she inherits a mutation from his/her parents; and how different tissues in the body get exposed to different mutagens, thus causing different types of cancer.

Type: Lesson Plan

This lesson uses the fundamentals of protein synthesis as a context for investigating the closest living relative to Tyrannosaurus rex and evaluating whether or not paleontologist and dinosaur expert, Jack Horner, will be able to "create" live dinosaurs in the lab. The first objective is for students to be able to access and properly utilize the NIH's protein sequence database to perform a BLAST, using biochemical evidence to determine T rex's closest living relative. The second objective is for students to be able to explain and evaluate Jack Horner's plans for creating live dinosaurs in the lab. The main prerequisite for the lesson is a basic understanding of protein synthesis, or the flow of information in the cell from DNA to RNA during transcription and then from RNA to protein during translation. You will find downloadable handouts of the necessary documents for the lesson. To complete the lesson, you will need the handouts and ideally computers with Internet connections so that students can complete the BLAST on their own or in groups. The computers are not a requirement, however, because the video has an optional segment that goes through the BLAST step-by-step and shows students exactly what they would see if they were doing it themselves. There is an optional reading assignment from WIRED magazine at the close of the lesson, and the article can be accessed for free on-line at . The lesson should take somewhere around 90 minutes, a portion of which is group or classroom discussion based on prompts from the video or the handouts.

The main focus of this MEA is to recognize the consequences of a catastrophic event, and understand the environmental and economical impact based on data analysis. Students will conduct individual and team investigations in order to arrive at a scientifically sound solution to the problem.

Model Eliciting Activities, MEAs, are open-ended, interdisciplinary problem-solving activities that are meant to reveal students’ thinking about the concepts embedded in realistic situations. MEAs resemble engineering problems and encourage students to create solutions in the form of mathematical and scientific models. Students work in teams to apply their knowledge of science and mathematics to solve an open-ended problem while considering constraints and tradeoffs. Students integrate their ELA skills into MEAs as they are asked to clearly document their thought processes. MEAs follow a problem-based, student-centered approach to learning, where students are encouraged to grapple with the problem while the teacher acts as a facilitator. To learn more about MEAs visit: https://www.cpalms.org/cpalms/mea.aspx

Scientists who are working to discover new medicines often use robots to prepare samples of cells, allowing them to test chemicals to identify those that might be used to treat diseases. Students will meet a scientist who works to identify new medicines. She created free software that "looks" at images of cells and determines which images show cells that have responded to the potential medicines. Students will learn about how this technology is currently enabling research to identify new antibiotics to treat tuberculosis. Students will complete hands-on activities that demonstrate how new medicines can be discovered using robots and computer software, starring the student as "the computer." In the process, the students learn about experimental design, including positive and negative controls. Students should have some introductory knowledge about the following topics: (1) biology: students should have a basic understanding of infection and good hygiene, they should know what bacteria and cells are; (2) chemistry: the students should know what a chemical compound (molecule) is. They should have an understanding that medicines, also called "drugs", are chemical compounds; (3) basic experimental design: students should understand the terms "samples" and "testing". All hand-outs necessary for this video lesson can be downloaded below.

This virtual lab has three components: a short tutorial describing meiosis, a series of microscope slides allowing students to identify stages of meiosis, and a karyotyping activity. The first components support student understanding of mitosis and meiosis, as well as gamete formation. The karyotyping activity is fun and interesting for students, but is not necessary for mastery of NGSS science benchmarks.

The lac operon is a set of genes which are responsible for the metabolism of lactose in some bacterial cells. Students will explore the effects of mutation within the lac operon by adding or removing genes from the DNA.

• Predicts the effects on lactose metabolism when the various genes and DNA control elements are mutated (added or removed).
• Predicts the effects on lactose metabolism when the concentration of lactose is changed.
• Explain the roles of Lacl, LacZ, and LacY in lactose regulation.

This is a simplified, interactive demonstration of genetic principles. Using a fictional species named the Norn, students can predict the outcome of genetic crosses (mono and di-hybrid, sex-linked, and multiple-allele). This could be used to strengthen the students understanding of genetics, practice Punnet squares, or practice calculation of genotypic/phenotypic ratios. However, it is unlikely to be useful as an independent assignment (if used as designed).

This is a lab/activity that uses dragons as "research subjects" for genetics research. It highlights independent assortment as well as gene linkage. Students will do the first part of the activity using independent assortment (genes on different chromosomes). The second part of the activity looks at genes on the same chromosome, and how linkage plays a part in allele assortment. It can be used to show how crossing over allows increased variation when involving linked genes.

Worksheets are available in both Word and PDF formats, for both teacher and student. There is an additional dragon genetics lab that illustrates the principles of Mendelian genetics as a whole.
