Teacher Name: - Weebly
Teacher Name: Ann Schultz
Class and Grade Taught: Honors Biology for 9th through 12th grades, Regular Biology for 9th through 12th grades
Lesson Dates: November 14-18, 2011
Unit Topic: Completion of Diffusion, Osmosis and Cellular Transport; Introduction to DNA
Unit Objectives: Explain how the processes of diffusion, osmosis, passive transport and active transport occur, and why they are important to cells. Explain how the genetic information encoded in DNA molecules provides instructions for assembling protein molecules, that genes are segments of DNA molecules, that inserting, deleting, or substituting DNA segments can alter genes, that an altered gene may be passed on to every cell that develops from it, and that the resulting features may help, harm, or have little or no effect on the offspring’s success in its environment. Protein synthesis begins with the information in a sequence of DNA bases being copied onto messenger RNA. This molecule moves from the nucleus to the ribosome in the cytoplasm where it is “read.” Transfer RNA brings amino acids to the ribosome, where they are connected in the correct sequence to form a specific protein.
Previous Lesson Topic: Diffusion, osmosis and cellular transport
Current Lesson Topics: Complete study of viruses by watching final part of video “And the Band Played On”, Complete study of diffusion, osmosis and cellular transport, Cornstarch and iodine semipermeable membrane lab, Gummy bear osmosis mini lab, Introduction to DNA through Discovery Education video, PowerPoint slides, interactive animations
Next Lesson Topic: Extend understanding of DNA, DNA extraction lab, DNA Web Quest, DNA models and activities
Lesson Objectives
Students will be able to:
Explain that molecules are constantly in motion
Describe how molecules move into and out of cells along a concentration gradient
Explain that cells are bounded by semi-permeable membranes
Explain how genetic information encoded in DNA molecules provides instructions for assembling protein molecules
Describe genes as segments of DNA molecules
Explain how inserting, deleting, or substituting DNA segments can alter genes
Describe how an altered gene may be passed on to every cell that develops from it, and how resulting features may help, harm, or have little or no effect on the offspring’s success in its environment
Describe the processes of transcription, translation and protein synthesis
Standards Addressed:
B1.2C Develop an understanding of a scientific concept by accessing information from multiple sources. Evaluate the scientific accuracy and significance of the information.
B1.2D Evaluate scientific explanations in a peer review process or discussion format.
B2.3A Describe how cells function in a narrow range of physical conditions, such as temperature and pH (acidity), to perform life functions.
B2.3B Describe how the maintenance of a relatively stable internal environment is required for the continuation of life.
B2.3C Explain how stability is challenged by changing physical, chemical, and environmental conditions as well as the presence of disease agents.
B4.2B Recognize that every species has its own characteristic DNA sequence.
B4.2C Describe the structure and function of DNA.
B4.2D Predict the consequences that changes in the DNA composition of particular genes may have on an organism (e.g., sickle cell anemia, other).
B4.2f Demonstrate how the genetic information in DNA molecules provides instructions for assembling protein molecules and that this is virtually the same mechanism for all life forms.
B4.2g Describe the processes of replication, transcription, and translation and how they relate to each other in molecular biology.

Flashcards
DNA – deoxyribonucleic acid
DNA – stores and transmits genetic information from one generation to the next
Structure of DNA – double helix with diagram
Nitrogenous bases for DNA – adenine (A), guanine (G), cytosine (C), thymine (T)
Base pairing rules for DNA – A–T, G-C
Replication – the double helix unzips and forms a new complementary strand on both sides
RNA – ribonucleic acid
RNA – acts as a messenger between DNA and the ribosomes to carry out protein synthesis
Nitrogenous bases for RNA - adenine (A), guanine (G), cytosine (C), uracil (U)
Base pairing rules for RNA – A-U, G-C
