The shape of a protein determines its function. In this lab, students will be given a hypothetical DNA sequence for part of an enzyme. The structure and function of enzymes is a central theme in cellular and molecular biology.
In this laboratory exercise, a crude cell extract is prepared from potatoes.DNA Structure
This lab uses two different sizes of dialysis tubing to represent cellular and organelle membranes. Students design experiments in which they place solutions of iodine, starch, and glucose on different sides of a membrane.Rt 809f
The movement of these materials is monitored with the use of indicator solutions. Students will cut DNA with restriction enzymes. Students can learn how this type of evidence is prepared and interpreted. A fluorescent probe is then washed over the gel. Students build a model insect based upon genetic information provided to them in the lab directions. Gene forms alleles contributed by each parent are determined by tossing a coin with one side representing the dominant form of the gene and the other side representing the recessive form.
Students will identify the parts of a microscope. Students will observe, manipulate, write and memorize. Students will also compute total magnification of the objective lenses. The lab can be modified to suit higher grade levels using the attached handouts for various observation stations.
PAGE is a powerful analytical technique having numerous applications in modern biology. Evidence for evolutionary relatedness amongst organisms can be determined using this technique. Protein synthesis occurs in ribosomes found in the cytoplasm and on rough endoplasmic reticulum.
If protein is to be synthesized, then the genetic information in the nucleus must be transferred to these ribosomes. Lab 1 Goal: To introduce students to the incredible diversity and abundance of insects and to prepare specimens for DNA analysis. Upon completion of this activity, students will: Describe the diversity of insects collected in one location.

Main Navigation. Catalase High School Molecular Biology The structure and function of enzymes is a central theme in cellular and molecular biology. Hosted by CampusPress.Students often struggle with understanding the theory of evolution. Many learn concepts better through hands-on activities to supplement lectures or discussions.
This game has several parallels to aspects of evolution. Students will enjoy modeling how microevolution can change a species over time. For perspective on how long life has been evolving, students measure the distance from the point where life first appeared to the appearance of humans or the present day and calculate how many years that has taken. Imprint fossils are made when organisms leave impressions in mud, clay, or other soft material that hardens over time. By examining fossils, scientists can determine how life has changed through evolution.
Making imprint fossils in class, students see how these fossils outline the history of life. Half-life, a way of determining the age of substances, is the time it takes for half the atoms in a radioactive sample to decay. Roughly half the pennies will show tails. Remove those pennies to illustrate that a new substance, "headsium," has been created in 15 seconds, the "half-life.

Use Belbin Team Roles to help build high-performing teams, maximize working relationships, and to enable people to learn about themselves.
Engage and develop the talent that is already around you. Foundation to build better approaches for decision-making, conflict and daily execution. Leadership DNA helps measure our impact, strengths, and weaknesses when working as a leader or manager. Intelligent and effective leadership is best underpinned with pragmatic knowledge of your operating style and those of others. Insight into how you and others will manifest such traits under pressure is of great use when leading or managing others or working in a leadership team.
Team DNA is made up of the unique behavioral clusters that all of us project when working with others. The way we contribute, interrelate and behave is based on a lifetime of unique experience, role learning, and personality that equips us with the mix of Team DNA that we use. Knowing our individual and collective Team DNA helps people and teams understand their strengths and weaknesses, make better decisions, avoid unnecessary friction and perform better. Teams need the unique talents and experience of all their members.
Every person performs some tasks quite naturally and effectively and will typically be not as adequate at other tasks.
5 Classroom Activities That Demonstrate the Theory of Evolution
A team role is defined as a way in which we prefer to interrelate with the team. We will usually have more than one as a preference. They are described in the Belbin team building questionnaire profile as preferred, manageable and least preferred. It is based on extensive research undertaken by Dr.

Meredith Belbin. During this research, it became evident that teams comprising a balance of mixed team roles outperform teams without this balance. Participants complete their own online profile and can then invite numerous observers from the workplace to offer style feedback to create a complete individual profile with up to 8 insightful reports on their unique operating style.
We analyze these profiles and can create detailed team combination reports for the total team and any nominated sub-teams or working relationships within the team.Although no charge or fee is required for using TeachEngineering curricular materials in your classroom, the lessons and activities often require material supplies. The expendable cost is the estimated cost of supplies needed for each group of students involved in the activity.

Students model DNA using gumdrops and toothpicks. Biomedical engineers study which specific DNA sequences code for certain characteristics as they investigate genetic disorders such as color blindness, Down syndrome, cystic fibrosis and hemophilia.
Engineers develop technologies to recognize certain DNA mutations. Biomedical engineers study genes and DNA to develop technologies that could manipulate or replace genes that are damaged or missing. Gene therapy has many implications for the diagnosis, treatment and possibly prevention of human diseases such as cancer, cystic fibrosis and heart disease.
Each TeachEngineering lesson or activity is correlated to one or more K science, technology, engineering or math STEM educational standards. In the ASN, standards are hierarchically structured: first by source; e.

As a class, students work through an example showing how DNA provides the "recipe" for making human body proteins. They see how the pattern of nucleotide bases adenine, thymine, guanine, cytosine forms the double helix ladder shape of DNA, and serves as the code for the steps required to make gene Students learn how engineers apply their understanding of DNA to manipulate specific genes to produce desired traits, and how engineers have used this practice to address current problems facing humanity.
Students fill out a flow chart to list the methods to modify genes to create GMOs and example a Students learn about mutations to both DNA and chromosomes, and uncontrolled changes to the genetic code. They are introduced to small-scale mutations substitutions, deletions and insertions and large-scale mutations deletion duplications, inversions, insertions, translocations and nondisjunction After watching video clips from the Harry Potter and the Goblet of Fire movie, students explore the use of Punnett squares to predict genetic trait inheritance.

Each time one of your cells divides, it must first copy the genetic information contained within its nucleus. In order to speed up the copying process, DNA replication begins at multiple locations along each chromosome. The two DNA strands are pulled apart and copied in both directions at the rate of about 50 nucleotides per second.Carehawk distributors
It would take nearly 5, strands of DNA laid side by side to equal the width of a human hair. At the magnification shown here about 7 million Xan average human chromosome would be about kilometers miles long, or roughly the distance between San Francisco and Los Angeles, CA.
These models are based on the molecular structure of real nucleotides. The grey and white circles on the models represent partial positive and negative charges that form hydrogen bonds between complementary bases. These bonds work kind of like tiny magnets to hold the two DNA strands together. Complementary base-pairing ensures that DNA strands are copied accurately, with just a few errors for each round of replication. Forces between neighboring nucleotides stack the bases on top of one another and twist the DNA strands into a double-helix.
