Gene Expression Essentials
Students transcribe DNA samples from the alien species called unigriffins- which are hybrids among birds, lions, and horses and can have a mix of traits from each.
Lesson Plans IndividualActivitiesMinilessons. This breakout escape room is a fun way for students to improve their skills and knowledge of protein synthesis.While the students work on the journal, I circulate through the room reading their responses. Several of the students had difficulty with this particular journal, so when it was time for volunteers to share their thoughts with the class, there were very few volunteers.
I try shifting gears, and ask the students whether or not DNA is important. They agree that it is important, so I ask them why. The students are able to explain that DNA is genetic material inherited from parents. I ask them to explain why this is important and the specific role DNA plays in the development of traits. The students are then able to articulate that DNA is the code that tells cells which proteins to make.
I ask the students to take out their DNA flipped notes and we review the steps of protein synthesis as well as DNA replication. I have the students add to their notes as necessary and address any questions they have along the way. After reviewing the basic steps of protein synthesis, I have the students open their Chromebooks and find the DNA Transcription and Translation document in Google Classroom. I review the instructions with the students and then I begin leading them through the first website.
I walk students through the slides, step-by-step, to ensure that they hear and see the information. Doing this also provides them with an opportunity to ask questions and allows me to add or clarify information to ensure their understanding.
I begin with the general overview of what happens during transcription and translation. Some of the students have a difficult time understanding the concept of transcription, so I try to use analogies to help them better understand. For instance, many of my students have siblings, so I compare DNA's inability to leave the nucleus to being grounded and unable to leave their room. I then compare the mRNA to their sibling or a text message sent to their parents in the hopes of achieving a desired outcome the creation of a protein.
This analogy is flawed, and we review the ways in which this model is and is not similar to transcription. I also lead the students through the translation portion of the activity, paying specific attention to the codons. One of the reasons for using the websites in this lesson is because they provide students with models of DNA and the translation and transcription process. One basic item that I point out to the students is the use of color and that the colors in the model are not necessarily representative of actual coloration.
We also discuss the difference in the amount of time it takes to complete the simulation versus the time it takes for the processes to occur in the cell. This video provides an overview of the websites used during this lesson.This lesson builds on the foundational knowledge that students will need to know in order to address the following inheritance and variation standards:. Develop and use a model to describe why asexual reproduction results in offspring with identical genetic information and sexual reproduction results in offspring with genetic variation.
Knowledge of the structure and as a result the function transcription, translation of DNA is required knowledge to understand both effects of genetic mutations, asexual, and sexual reproduction. The decoding of DNA is similar to this multi-step process. Another reason I choose this activity is that it connects to what my students are studying in World History.
In this activity students use a model to learn about transcription and see the relationship between DNA structure and this process. Learning Objectives after 2 day lesson. Day 1. Day 2. As students complete reading they answer the following questions:.
Having studied the process by which DNA directs the synthesis of proteins, you should be ready to decode some DNA "secret" messages. To do this, you must follow the procedure of protein synthesis as this is taking place right now in your cells; no short cuts! Practice these steps by following and finishing the partially solved message below. For purposes of simplicity, it will be assumed that this mRNA is bacterial; there are no introns to cut out!
The purpose of this activity is to assess student comprehension of DNA transcription. The formation of the correct mRNA sequence is needed for correct translation of protein which is the topic of next lesson. Empty Layer. Home Professional Learning. Professional Learning.

Resources for Teaching about Coronavirus has descriptions and links for multiple resources to use in teaching and learning about coronavirus. This page also includes some resources for teaching remotely. Download all of the PDFs in a zipped archive. Caveat: file size is about MB and will take a while. The expression " hands-on, minds-on " summarizes the philosophy we have incorporated in these activities - namely, that students will learn best if they are actively engaged and if their activities are closely linked to understanding important biological concepts.
Many of our activities are explicitly aligned with the Next Generation Science Standardsas indicated by NGSS in the descriptions below and the links to the right.
Additional information is provided in Summary Tables and in the Teacher Preparation Notes for these activities. To accommodate limited budgets, most of our activities can be carried out with minimum equipment and expense for supplies. Additional resources for teaching biology are available at Minds-on Activities for Teaching Biology. These teaching resources include analysis and discussion activities, games, and overviews of important biological topics, including major concepts, common misconceptions, and suggested learning activities.
Is Yeast Alive? Students evaluate whether the little brown grains of yeast obtained from the grocery store are alive by testing for metabolism and growth. In this hands-on, minds-on activity, students investigate the biological causes of Maria's symptoms and Jayden's symptoms. To explore the causes of these symptoms, students carry out two experiments and interpret the results, and they answer additional analysis and discussion questions. Students learn about enzyme function and enzyme specificity as they figure out that Maria's symptoms are due to lactase deficiency resulting in lactose intolerance and Jayden's symptoms are due to sucrase deficiency.
In the final section, students are challenged to generalize their understanding of enzymes to interpret a video of an experiment with saliva, starch and iodine. This activity can be used in an introductory unit on biological molecules or later in the course during a discussion of enzymes. In this activity, students first learn about the structure and functions of starch and protein and the basics of the synthesis of starch, amino acids and proteins.
Then, students learn about scientific investigation by carrying out key components of the scientific method, including developing experimental methods, generating hypotheses, designing and carrying out experiments to test these hypotheses and, if appropriate, using experimental results to revise the hypotheses.

This is known collectively as the human genome. The human genome contains around 30 genes, each of which codes for one protein. Large stretches of DNA in the human genome are transcribed but do not code for proteins.
The nucleotide sequence of the human genome is now known to a reasonable degree of accuracy but we do not yet understand why so much of it is non-coding. Some of this non-coding DNA controls gene expression but the purpose of much of it is not yet understood. This is a fascinating subject that is certain to advance rapidly over the next few years. Each time a cell divides, each of its double strands of DNA splits into two single strands.
Each of these single strands acts as a template for a new strand of complementary DNA. As a result, each new cell has its own complete genome. This process is known as DNA replication.
Replication is controlled by the Watson-Crick pairing of the bases in the template strand with incoming deoxynucleoside triphosphates, and is directed by DNA polymerase enzymes. It is a complex process, particularly in eukaryotes, involving an array of enzymes.
A simplified version of bacterial DNA replication is described in Figure 2. This makes it impossible for DNA polymerases to synthesize both strands simultaneously.Transcription and mRNA processing - Biomolecules - MCAT - Khan Academy
A portion of the double helix must first unwind, and this is mediated by helicase enzymes. The leading strand is synthesized continuously but the opposite strand is copied in short bursts of about bases, as the lagging strand template becomes available.
The resulting short strands are called Okazaki fragments after their discoverers, Reiji and Tsuneko Okazaki. Pol III can then take over, but it eventually encounters one of the previously synthesized short RNA fragments in its path.
The initiation of DNA replication at the leading strand is more complex and is discussed in detail in more specialized texts. DNA replication is not perfect. This leads to mismatched base pairs, or mispairs. DNA polymerases have proofreading activity, and a DNA repair enzymes have evolved to correct these mistakes. Occasionally, mispairs survive and are incorporated into the genome in the next round of replication. These mutations may have no consequence, they may result in the death of the organism, they may result in a genetic disease or cancer; or they may give the organism a competitive advantage over its neighbours, which leads to evolution by natural selection.
Transcription is the process by which DNA is copied transcribed to mRNA, which carries the information needed for protein synthesis. Transcription takes place in two broad steps. The mechanism of transcription has parallels in that of DNA replication. As with DNA replication, partial unwinding of the double helix must occur before transcription can take place, and it is the RNA polymerase enzymes that catalyze this process.
Unlike DNA replication, in which both strands are copied, only one strand is transcribed. The strand that contains the gene is called the sense strand, while the complementary strand is the antisense strand. The mRNA produced in transcription is a copy of the sense strand, but it is the antisense strand that is transcribed.
Transcription ends when the RNA polymerase enzyme reaches a triplet of bases that is read as a "stop" signal. The DNA molecule re-winds to re-form the double helix. The pre-messenger RNA thus formed contains introns which are not required for protein synthesis.
