In some cyanobacteria, many nucleoids may accumulate in an enlarged round cell or along a filament, leading to the generation of many new cells at once. The new cells often split from the parent filament and float away in a process called fragmentation (Figure 15). Fragmentation is commonly ...
It is said that no animal cell divides while ciliated [1, 2]. Although many protists retain motile cilia as they divide, in proliferative animal cells the single motile or non-motile cilium must be resorbed during mitosis, then regenerated [3–5]. The sole exceptions we know of are the ...
During mitosis, many proteins dissociate from chromatin and transcription shuts down. This may favour a silent PRE but challenge an active one. Several PcG and TrxG proteins remain bound to mitotic chromatin and may 'bookmark' silent and active states. Many PcG and TrxG target genes are dynami...

When the elementary student first studies mitosis it is usually about the details of what happens, at the cellular and biochemical level. Here we look at the same problem, but at the other end of the conceptual gradient. When a cell divides, again and again, what does that imply abo...
Almost all cells in the body divide. This is how organisms grow and adapt. During that process, called mitosis, the original cell's genetic material—in the form of chromosomes—is equally distributed or "segregated" between two identical daughter cells. When it doesn't go smoothly, chromosome...
A triploid cell in humans would have how many chromosomes? How many chromosomes are there in human cells formed by mitotic cell division and meiotic cell division? How many cell divisions occur for the production of a gamete? How much DNA does a cell have after meiosis? What is the diplo...
