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 ...

Researchers in Japan have discovered that the local DNA motion inside of human cells remains steady throughout interphase, where the cell grows and replicates its DNA for cell division. The study ...

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 ...

In order for organisms to grow, cells have two options: they must either replicate themselves to create more cells, or the cells themselves must expand in volume. In humans, tissues such as the skin ...

Rather than dividing while rounding up into perfect balls, as often seen in the division of other cells, these cells maintained their rod shape, leading to the creation of offspring cells that ...

In the process of replicating themselves, cells have another choice: do they want to make an identical copy and be left with two cells? Or do they want to make four “half-copies”, in preparation for ...
