The five phases of mitosis and cell division tightly coordinate the movements of hundreds of proteins. How did early biologists unravel this complex dance of chromosomes? The most obvious difference ...

During interphase, the cell's DNA is not condensed and is loosely distributed. A stain for heterochromatin (which indicates the position of chromosomes) shows this broad distribution of chromatin in a ...

Interphase is the period between cell divisions. During this time, chromosomes replicate—each DNA strand unzips into two strands while free-floating bases attach to the unzipped strands. The ...

This activity and guide has been thoughtfully designed to help you fully understand exactly what's happening at every stage of mitosis. Mitosis will produce two daughter cells which are genetically ...

This activity has been carefully designed to help you see and understand exactly what’s happening during each stage of mitosis. Mitosis will produce two daughter cells which are genetically identical ...

Until now, cells dividing by mitosis were thought to grow round and then split into two identical, spherical daughter cells. New research has found that some cells are isomorphic, meaning they retain ...

The chromosomes do not replicate during this phase, as they do in interphase in mitosis and interphase I in meiosis.
