Daughter in Biological Definition

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 ...

Then his treasured daughter Annie fell ill, reawakening his fears that his ... animal bones dominated, but when with his ill daughter at a seaside resort he became absorbed in the ... agnostic , particularly after the death of his daughter Anne . A popular Christian urban legend ...

Extinction

... may or may not exist for extinct species. 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. ...

Mitosis

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 ...

Carolus Linnaeus

... should be proud to nurse their own children). 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 . Crescentin The bacterium Caulobacter crescentus ...

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 ...

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. ...
