It will also be served and upgraded at http://www.cell-biology.org/ Many of the photos taken from texts used by our students. These are used as supplemental handouts and guides for the discussions in our lectures. Most of these topics focus on structure/function correlations. They are not intended to be comprehensive. Some topics, like those focusing on mitochondria, will correlate with biochemistry and physiology lectures that expand students' understanding of that organelle system.

The discovery of how one tiny component of the motor protein kinesin powers its movement represents an important insight into one of the most fundamental aspects of biology.

Before partitioning can occur, the chromosomes must become aligned so that the separation process can occur in an orderly fashion. The alignment of replicated chromosomes and their separation into two groups is a process that can be observed in virtually all eukaryotic cells. Both the alignment and separation processes are the consequen Read More Go to Site

		The Cell Cycle ^Votes:0 The Cell Cycle Index to this page Control of the Cell Cycle Steps in the Cycle Meiosis and the Cell Cycle Checkpoints in the Cycle p53 ATM MAD G 0 A eukaryotic cell cannot divide into two, the two into four, etc. unless two processes alternate: doubling of its genome ( DNA ) in S phase (synthesis phase) of the cell cycle; halving of that genome during mitosis ( M phase ). The period between M and S is called G 1 ; that between S and M is G 2 . So, the cell cycle consists of: G 1 = growth and preparation of the chromosomes for replication; S = synthesis of DNA [see DNA Replication ] and duplication of the centrosome ; G 2 = preparation for M = mitosis . When a cell is in any phase of the cell cycle other than mitosis, it is often said to be in interphase . Control of the Cell Cycle The pass Read More Go to Site

		The Cell Membrane ^Votes:0 University of Texas Medical Branch Cell Biology Graduate Program Membrane Structure The cell is highly organized with many functional units or organelles. Most of these units are limited by one or more membranes. To perform the function of the organelle, the membrane is specialized in that it contains specific proteins and lipid components that enable it to perform its unique roles for that cell or organelle. In essence membranes are essential for the integrity and function of the cell. Membrane components may: be protective regulate transport in and out of cell or subcellular domain allow selective receptivity and signal transduction by providing transmembrane receptors that bind signaling molecules allow cell recognition provide anchoring sites for cytoskeletal filaments or components of Read More Go to Site

		The Rockefeller University Journey Into the Cell ^Votes:0 Celebrating 50 Years of Electron Microscopy and Modern Cell Biology Journey Into the Cell "The key to every biological problem must finally be sought in the cell," wrote the great classical cell biologist, E.B. Wilson, in 1925. Yet at the time Wilson wrote, the world inside the cell was largely inaccessible. The primary instrument of investigation for classical cell biologists--the light microscope--was physically incapable of resolving a cell's fine interior details. Albert Claude compared the situation encountered by Wilson and his contemporaries to that faced by astronomers, "who were permitted to see the objects of their interest, but not to touch them; the cell was as distant from us as the stars and galaxies...." Indeed, before the advent of modern cell biology, pioneered by Claude a Read More Go to Site
