Cell (biology)
The cell (from Latin cella, meaning "small room") is the basic structural, functional, and biological unit of all known living organisms. Cells are the smallest unit of life that can replicate indepen...

Mitosis vs. Meiosis: Key Differences, Chart and Venn Diagram | Technology Networks
Mitosis and meiosis are two kinds of cell division that are essential to most forms of life on earth. Here we investigate the key differences and similarities between the two processes.

A One-Day Starvation Secret Got the Nobel Prize
You probably know that most tissues in your body regularly replace their cells with new ones. Different organs need their own time to renew completely. And some tissues don't replace their cells at al...

Age-related loss of intestinal stem cell function can be reversed by a 24-hour fast.
Here’s How Stanford Scientists Measured the Speed of Death
For the first time ever, scientists at Stanford University have been able to observe the speed at which death spreads across a cell once the self-destruct 'trigger wave' has been initiated. Their conc...

Biology: Cell Structure
This animation shows you the function of plant and animal cells for middle school and high school biology, including organelles like the nucleus, nucleolus, DNA (chromosomes), ribosomes, mitochondria,...
The Workhorse of the Cell: Kinesin
Masterpieces of microengineering, kinesins are motorized transport machines that move cellular materials to their correct locations in the cell so they can perform their functions. Kinesins have two f...
Drew Berry: Animations of unseeable biology
http://www.ted.com We have no ways to directly observe molecules and what they do -- Drew Berry wants to change that. At TEDxSydney he shows his scientifically accurate (and entertaining!) animations ...
A Day in the Life of a Motor Protein
The primary aim of the Hoogenraad research lab at the University of Utrecht, the Netherlands, is to understand how intracellular protein transport underlies the development and function of nerve cells...
Prokaryote
3D animation of a prokaryotic cell that shows all the elements that compose it.A prokaryote is a single-celled organism that lacks a membrane-bound nucleus (karyon), mitochondria, or any other membr...
Eukaryote
A eukaryote (/juːˈkæri.oʊt/ yoo-KARR-ee-oht) is any organism whose cells contain a nucleus and other organelles enclosed within membranes.Eukaryotes belong to the taxon Eukarya or Eukaryota. The defin...
Cell biology
Cell biology (formerly cytology, from the Greek kytos, "contain") is a branch of biology that studies cells – their physiological properties, their structure, the organelles they contain, interactions...
Cellular processes
The cell (from Latin cella, meaning "small room") is the basic structural, functional, and biological unit of all known living organisms. Cells are the smallest unit of life that can replicate indepen...
Evolution of cells
The evolution of cells refers to the evolutionary origin and subsequent evolutionary development of cells. Cells first emerged at least 3.5 billion years ago.
The origin of cells was the most impo...
Cell cycle
The cell cycle, or cell-division cycle, is the series of events that take place in a cell leading to its division and duplication (replication) that produces two daughter cells. In cells without a nuc...
Interphase
Interphase is the phase of the cell cycle in which the cell spends and performs the majority of its time. Then, in preparation for cellular division, it increases in size. Interphase is also considere...
Cell division
Cell division is the process by which a parent cell divides into two or more daughter cells. Cell division usually occurs as part of a larger cell cycle. In eukaryotes, there are two distinct types of...
Apoptosis
Apoptosis (/ˌæpəˈtoʊsɪs/; from Ancient Greek ἀπό apo, "by, from, of, since, than" and πτῶσις ptōsis, "fall") is the process of programmed cell death (PCD) that may occur in multicellular organisms. Bi...
Gene expression
Gene expression is the process by which information from a gene is used in the synthesis of a functional gene product. These products are often proteins, but in non-protein coding genes such as transf...
Protein biosynthesis
Protein Biosynthesis refers to the process whereby biological cells generate new proteins; it is balanced by the loss of cellular proteins via degradation or export. Translation, the assembly of prote...
DNA repair
DNA repair is a collection of processes by which a cell identifies and corrects damage to the DNA molecules that encode its genome. In human cells, both normal metabolic activities and environmental f...
Programmed cell death
Programmed cell-death (or PCD) is death of a cell in any form, mediated by an intracellular program. PCD is carried out in a regulated process, which usually confers advantage during an organism's lif...
