Cell growth
... cell (the "parental" cell) divides to produce
daughter cells . In other contexts, "cell growth" refers ... mitosis. Both lead to the production of two
daughter cells with the same number of chromosomes as the ... of diploid organisms. It produces four special
daughter cells ( gametes ) which have half the normal ...

Extinction

daughter species that evolve from a parent species carry ... though the parent species may become extinct, the
daughter species lives on. In other cases, species have ...
Extinction of a parent species where
daughter species or subspecies are still alive is also ...
Meiosis
... which a diploid parent produces four haploid
daughter cells. The process includes the two stages of ... when the centromeres arrive at the poles. Each
daughter cell now has half the number of chromosomes but ... cells and presents no DNA replication.
Two
daughter cells are formed by the end of Telophase I.

Anaphase
... holding sister chromatids together. They immediately separate, marking the cytological onset of anaphase. After separation they are referred to as
daughter chromatids.
Within anaphase two distinct processes occur. During anaphase A the chromatids abruptly separate and move towards the spindle poles. ...
Barr body
... tissues of some placental mammals, in which the father's X chromosome is always deactivated.
The inactivation state of chromosomes is passed on to
daughter cells during mitosis. Since random chromosomes are selected for inactivation early in embryonic development, this results in different regions of the ...
Bacterium
... asexually , not sexually . Specifically they reproduce by binary fission , or simple cell division. During this process, one cell divides into two
daughter cells with the development of a transverse cell wall.
However, independent of sexual reproduction, genetic variations can occur within individual ...

Autograph of Carl v. Linn (Carolus Linnaeus)
In 1739 Linnaeus married Sara Morea,
daughter of a physician. He ascended to the chair of medicine at Uppsala two years later, soon exchanging it for the chair of Botany. He continued to work on ...
Cell division
... Cell division is the process of a biological cell (called a mother cell ) dividing into two
daughter cells . This leads to growth in multicellular organisms (the growth of tissue ) and to procreation ( vegetative reproduction ) in unicellular ...
Centromere
... centromeres with no α-satellite DNA.
Epigenetic inheritance plays a major role in specifying the centromere in most organisms. The
daughter chromosomes will assemble centromeres in the same place as the parent chromosome, independent of sequence. However, there must still be some ...
Chromosome
... are attached at the centromere and two opposite ends of the cell. During mitosis, the microtubules pull the chromatids apart, so that each
daughter cell inherits one set of chromatids. Once the cells have divided, the chromatids are uncoiled and can function again as chromatin. In spite of their ...
Cytoskeleton
... system that involves an actin-like protein ParM . Filaments of ParM exhibit dynamic instability , and may partition plasmid DNA into the dividing
daughter cells by a mechanism analogous to that used by microtubules during eukaryotic mitosis .

Eukaryote
... Reproduction
Nuclear division is often coordinated with cell division . This generally takes place by mitosis , a process which allows each
daughter nucleus to receive one copy of each chromosome. In most eukaryotes there is also a process of sexual reproduction, typically involving an alternation ...
Metaphase
... in the eukaryotic cell cycle in which condensed chromosomes align in the middle of the cell before being separated into each of the two
daughter cells.
One of the cell cycle "checkpoints " occurs during metaphase. Only after all chromosomes have become aligned at the metaphase plate does ...
Mitotic spindle
... chromatids pointing to opposite ends of the spindle, the sister chromatids separate and are dragged away from each other, ensuring that each
daughter cell will receive one chromatid after the cells divide in cytokinesis .
...
Peroxisome
... membrane proteins that are critical for various functions, such as for importing proteins into their interiors and to proliferate and segregate into
daughter cells.
Peroxisomes function to rid the cell of toxic substances, such as hydrogen peroxide , or other metabolites and contain enzymes ...
Plasmid
... danger of being lost in one of the segregating bacteria. Such single-copy plasmids have systems which attempt to actively distribute a copy to both
daughter cells.
Some plasmids include an addiction system . They produce both a long-lived poison and its short-lived antidote . The cell that keeps a ...
Prophase
... but are called chromosomes again. The task of mitosis is to assure that one copy of each sister chromatid - and only one copy - goes to each
daughter cell after cell division.
The other important piece of hardware in mitosis is the centriole , which serves as a sort of anchor. During prophase, ...
Replication
... molecule (or any other pattern) making a copy of itself.
DNA replication is the act of copying the genetic material of a cell ( DNA ) to a
daughter cell is almost, but not quite, a form of self-replication because it requires the cellular apparatus to perform that replication.
