In this activity, students learn about the Human Genome Project. They do an interactive Web activity which simulates the process scientists use to determine the sequence of chromosomal DNA bases. Then they learn how two teams of scientists raced to decode the human genome. Next they explore a stretch of sequenced DNA on the Web to learn about the function of different sections of DNA code. They learn how knowledge of the human genome is being applied to medicine. They also learn about genetic variation among humans and between humans and other species. Finally, they assess what they have learned about the Human Genome Project by playing a game of Jeopardy.

Do a wet lab in which students extract their own DNA from a cheek cell (see Extract Human DNA from Cheek Cells activity).

The Lesson

Part I

1. Show the Human Genome Project video. Discuss the following:

What does the Human Genome Project decode?

How is that code represented?

What has the project revealed about the differences between humans and bananas?

What questions does the Human Genome Project raise for you?

2. Now have students explore the DNA sequencing process by doing the Web activity Sequence for Yourself. Use the following questions to elicit student responses, either in writing or as part of a whole-class discussion:

Why does the DNA have to be cut into pieces? How is this done?

How are DNA copies made in the lab?

How do primers and special fluorescent nucleotides help determine the DNA sequences?

How does the overlapping of DNA segments allow the entire sequence of a DNA molecule to be read?

3. Show video The Sequencing Race Begins. Ask:

What is the process for sequencing the human genome?

How has the way scientists read the genetic code changed in recent years?

Why is the map of the human genome considered only the beginning of the Human Genome Project?

4. Have students Explore a Stretch of Code and take notes as they do it. Then ask the following and discuss as a class:

What does the majority of the DNA in chromosomes code for?

What is the role of gene promoters like TATA boxes?

How does the "machinery" of the cell know where to begin reading the gene?

What are exons, and what is their function in the chromosomes?

What are introns, and what do they do? What happens to them when DNA is transcribed into mRNA?

What are the roles of "hitchhiking" and ancient code in human DNA, and where did they come from?

How alike is the DNA from two different humans?

What is a gene, and what role do genes play in the human body?

5. Show the video HIV Immunity to examine some of the benefits of mapping the human genome. Ask:

What are outliers, and what is their value in understanding disease?

How can a genetic mutation be advantageous?

How is the knowledge of mutations being used to combat the HIV virus?

6. Show the video Genetic Variation and discuss the following:

Whose genes are being sequenced in the two human genome projects?

Are these genes representative of the human species? Why or why not?

What is the percentage of genetic difference between any two humans?

What does the similarity of basic functions between different organisms indicate?

7. Finally, have students read the Genome Facts document. Have students use these facts and what they have learned about the Human Genome Project to create a series of answers and questions for a Jeopardy quiz show. (

Answer:

Charakan

Explanation:

The odd one out would be Charakan.

Theophrastus, Carl Linnaeus, and Aristotle are all scientists that contributed to the science of classification of living organisms (taxonomy).

Aristotle was the first scientist to classify living organisms into plant and animal kingdoms based on the artificial system of classification.

Theophrastus was a student of Aristotle and he wrote a book, De Historia Plantarum,  classifying about 480 plants.

Carl Linnaeus invented the binomial system of naming living organisms in which organisms are given two names - the species and the genus name.

Charakan has no known contribution to taxonomy. Hence, the name is the only odd one.

Answer:

a clone

Explanation:

Restriction enzymes are DNA-cutting enzymes. Each enzyme recognizes one or a few target sequences and cuts DNA at or near those sequences. Many restriction enzymes make staggered cuts, producing ends with single-stranded DNA overhangs. However, some produce blunt ends.

Answer:

Explanation:

The burning of fossil fuels releases greenhouse gases into the atmosphere, increasing levels of CO2 and other gasses, trapping heat, and contributing to global climate change. Coal combustion releases the greenhouse gases carbon dioxide (CO2) and nitrous oxide (N2O) during combustion. The major disadvantage of coal is its negative impact on the environment. Coal-burning energy plants are a major source of air pollution and greenhouse gas emissions. In addition to carbon monoxide and heavy metals like mercury, the use of coal releases sulfur dioxide, a harmful substance linked to acid rain.

Answer:

Air pollution

Can impact health of citizens like asthma, breathing difficulties, etc.

Can lead to death if not treated or fixed.

Releases greenhouse gases into the atmosphere.

Contributes to global climate change.

D. Trilobites

Trilobites made their entrance onto the Earth's stage during the late Cambrian Period. This is the first and oldest division of the Paleozoic Era.

Meiosis is the reductional division which creates four daughter cells that have identical genetic information to the parent cells. Thus, the correct option is C.

Meiosis is a special type of cell division which is also called as reductional division. This division takes place in the germ cells in sexually reproducing organisms which results into production of gametes, such as sperm or egg cells. Meiosis involves two rounds of division which ultimately result in the formation of four cells with only one copy of each chromosome or half genetic content.

Meiosis is divided into two divisions: Meiosis I and Meiosis II. In which, Meiosis II is similar to Mitosis and Meiosis I involves the reduction of genetic material to half.

Therefore, the correct option is C.

Answer:

decreases a plant’s weight

Explanation:

Aerobic respiration is a process of respiration in which oxygen is required and the byproducts of aerobic respiration are carbon dioxide, water and energy.

Plants undergo aerobic respiration and it is a catabolic process in which complex compounds in plants turns into simpler compounds. This process reduces the dry weight of the plants.

Glycolysis is the first step in both aerobic and anaerobic respiration so it is not a typical aerobic respiration.

Hence, the correct answer is "decreases a plant’s weight".

Answer:

The correct answer is - option B. laws that improve air quality and restrict pollution.

Explanation:

The dark peppered moths were the adaption of the light peppered moths due to the change in the environmental condition of increased pollution that made tree bark dark in color and allows birds to easily prey on the light peppered moths.

This leads to natural selection and light moths become dark but the after Clean Air Act was that there was less pollution then there is less soot in the air, so trees were less black which result in the Light-colored moths would increase, and dark-colored moths would decrease.

Answer:

The trait being described is the ability to fly in rainy season.

Explanation:

The trait being described is the ability to fly in rainy season. The people with bat wings and people with bird wings are present in the population. The event lead to the change in allele frequency because the population of people with bird wings die due to starvation. Yes, the bat wings were adapted to that environment so they are able to survive. The change make the population less similar to other populations because population of people with bat wings increases as compared to other population. Yes, the new population change for the better of the ecosystem because the population is able to controls the population of other species in the ecosystem.
