Active and Passive Transport: Red Rover Send Particles Over
Conditions of Use:
Read the Fine Print
Rating

Students compare and contrast passive and active transport by playing a game to model this phenomenon. Movement through cell membranes is also modeled, as well as the structure and movement typical of the fluid mosaic model of the cell membrane. Concentration gradient, sizes, shapes and polarity of molecules determine the method of movement through cell membranes. This activity is associated with the Test your Mettle phase of the legacy cycle.

Avoiding Genomic Instability: DNA Replication, the Cell Cycle, and Cancer, Fall 2006
Conditions of Use:
Remix and Share
Rating

In this class we will learn about how the process of DNA replication is regulated throughout the cell cycle and what happens when DNA replication goes awry. How does the cell know when and where to begin replicating its DNA? How does a cell prevent its DNA from being replicated more than once? How does damaged DNA cause the cell to arrest DNA replication until that damage has been repaired? And how is the duplication of the genome coordinated with other essential processes? We will examine both classical and current papers from the scientific literature to provide answers to these questions and to gain insights into how biologists have approached such problems. This course is one of many Advanced Undergraduate Seminars offered by the Biology Department at MIT. These seminars are tailored for students with an interest in using primary research literature to discuss and learn about current biological research in a highly interactive setting. Many instructors of the Advanced Undergraduate Seminars are postdoctoral scientists with a strong interest in teaching.

Biochemistry is the study of chemical processes within and related to living organisms. In this e-module you will learn about biomolecules and cell components, cell structure and subcellular compartments, DNA and RNA metabolism, and epigenetic mechanisms. This e-module was created as part of the Toxicology Mentoring and Skills Development Training (http://www.toxmsdt.com/) Program, a two-year pilot program funded by the National Institutes of Health.

In this e-module the following topics are available:
- Topic 1: Introduction to Biomolecules and Cell Components
- ​Topic 2: Cell Structure and Subcellular Compartments
- ​Topic 3: DNA and RNA Metabolism
​- Topic 4: Epigenetic Mechanisms

Biology is designed for multi-semester biology courses for science majors. It is grounded on an evolutionary basis and includes exciting features that highlight careers in the biological sciences and everyday applications of the concepts at hand. To meet the needs of today’s instructors and students, some content has been strategically condensed while maintaining the overall scope and coverage of traditional texts for this course. Instructors can customize the book, adapting it to the approach that works best in their classroom. Biology also includes an innovative art program that incorporates critical thinking and clicker questions to help students understand—and apply—key concepts.

Biology - Remixed for Austin Community College, The Study of Life

Life is all around us, both as multicellular organisms such as the iguana and bamboo above, as well as the unicellular microorganisms such as bacteria.  Life is present on every continent, in the air and in the waters of the world.  There is life even in the Mariana Trench, seven miles below the surface of the ocean.  As of 2010 biologists have described and classified 1.7 million plants and animals, and estimate that there are till over five million species still undiscovered.This chapter will introduce the ways we study the science of Biology in the twenty-first century, the characteristics of living organisms and their classification.

Living things are highly organized and structured, following a hierarchy that can be examined on a scale from small to large. The atom is the smallest and most fundamental unit of matter. It consists of a nucleus surrounded by electrons. Atoms form molecules. A molecule is a chemical structure consisting of at least two atoms held together by one or more chemical bonds. Many molecules that are biologically important are macromolecules, large molecules that are typically formed by polymerization (a polymer is a large molecule that is made by combining smaller units called monomers, which are simpler than macromolecules). An example of a macromolecule is deoxyribonucleic acid (DNA) (Figure 1.15), which contains the instructions for the structure and functioning of all living organisms.
