Lecture 04: Biochemistry 3
This course covers the fundamental principles of biochemistry, genetics, molecular biology, and cell biology. Biological function at the molecular level is particularly emphasized and covers the structure and regulation of genes, as well as, the structure and synthesis of proteins, how these molecules are integrated into cells, and how these cells are integrated into multicellular systems and organisms. In addition, each version of the subject has its own distinctive material. The focus of the c
Virtual laboratories in Molecular and Cell Biology - Intracellular signalling
A virtual laboratory which allows users to analyse intracellular signalling pathways. The programme allows the student to stimulate cells for different periods of time and analyse phosphorylation/activation of kinases in the signalling pathways, using SDS-PAGE and immunoblotting. Use of different cell types (dominant-negative mutants) and pull-down assays allows them to derive the hierarchy in the signalling pathways. The programme first introduces the theory behind the techniques. It then takes

The Embryo Takes Shape
Genes direct the development of a growing embryo. But not all genes in a cell are active at any given time. Sometimes a cell's location in the developing embryo determines which genes get turned on and which genes stay inactive. This video segment from NOVA: "Life's Greatest Miracle" explores the developmental process of an embryo beginning just two weeks after fertilization. Closed captioning included. Run time 07:47.
How does a single fertilized egg grow to become a fully formed human being? Many of the most critical stages happen in the first few days following conception. In this video segment from The Secret of Life, a fertilized egg cell progresses from its earliest stages through cell differentiation and ultimately the development of an embryo, with simple but identifiable body parts including a spinal cord, a heart, and eyes. Run time 01:20.

How Do Changes in the Earth's Lower Atmosphere Affect Us? - Continued
How do changes in Earth's lower atmosphere affect us? (continued) Jeff Thayer – University of Colorado continues the discussion of How do changes in Earth's lower atmosphere affect us? We are so dependent on our space assets, our satellites, cell phones and GPS. The atmosphere breathes and the satellite senses these changes and is impacted by it. We are very Earth centric, so we are just beginning to explore all there is of space. Run time 03:14.
Learn about Fuel Cell Technology
Many researches have been working on renewable, clean energy sources. This particular study shows how hydrogen may some day replace gasoline to fuel our vehicles with zero emission of fuel cells. Learn about real world testing of this fuel cell technology. Run time 01:50.
The Intel 386 Story for Kids
[Recorded Feb 4, 2009] Today, many American teenagers enjoy a life enriched by an almost pervasive level of technology. Teens live surrounded by laptop computers, gaming systems, cell phones, and DVD and MP3 music players. All of these technologies have been made possible through increasingly smaller, cheaper and more powerful microprocessors often developed and sold by Intel. In this lecture, Professor Richard Tedlow targets his talk at teenagers to explain a part of the microprocessor technolo
School Safety And Technology: Important Issues for All Schools
Beware of the ad that starts the video.
There are many issues that every school needs to address. Especially important is the privacy issues and what happens in an emergency and the lines are blocked from administration use
These issues are addressed in this short video:
How can cell phones impact school safety?
How can digital cameras impact school safety?
How can computers pose a threat to school safety?
What steps should schools take to protect s
Cell Phone Facts : How Do Cell Phones Work?
Beware of the ad at the beginning. Very political. Cell phones work by transmitting a signal to a tower, which in turn sends signals to either land lines to other towers. Find out why cell phones have trouble and how they work. World's worst artist does not help.
Deconstructing A Television Commercial: Media Literacy
Here is a classic mobile (cell) phone advertisement, which can be incorporated into media literacy instruction to teach the techniques of persuasion as well as the techniques of production. I have created a companion lesson plan which can be found here: (run time :59)
Parts of a Plant Cell
This short video explains each of the organelles inside a plant cell and especially addresses the organelles that differ from an animal cell. The video also briefly explains photosynthesis while discussing the chloroplasts in a plant cell. Run time 02:56
Plant Cell Motility and Laser Microsurgery of Cytoplasmic Strands
Plant cells are shaped by rigid cell walls. Osmotic forces press the plasma membrane tightly against these walls. The walls can be removed with enzymes. The remaining structures, the protoplasts, are now bordered by the plasma membrane. Since the shaping force of the wall is missing, isolated plant protoplasts are usually perfectly spherical in shape as a result of non-directional osmotic forces. Run time 04:19
