To return from a diploid stage to a haploid stage, meiosis must occur. (wikipedia.org)
Zygotic meiosis and gametic meiosis have one mitotic stage: mitosis occurs during the n phase in zygotic meiosis and during the 2n phase in gametic meiosis. (wikipedia.org)
Sporic meiosis, on the other hand, has mitosis in two stages, both the diploid and haploid stages, termed "diplobiontic" (not to be confused with diplontic). (wikipedia.org)
A zygotic meiosis is a meiosis of a zygote immediately after karyogamy, which is the fusion of two cell nuclei. (wikipedia.org)
Plasmodium) In rhizarians: some euglyphids, ascetosporeans In excavates: some parabasalids In amoebozoans: Dictyostelium In opisthokonts: most fungi (some chytrids, zygomycetes, some ascomycetes, basidiomycetes) In gametic meiosis, instead of immediately dividing meiotically to produce haploid cells, the zygote divides mitotically to produce a multicellular diploid individual or a group of more unicellular diploid cells. (wikipedia.org)
Cells from the diploid individuals then undergo meiosis to produce haploid cells or gametes. (wikipedia.org)
The diploid multicellular individual is a diplont, hence a gametic meiosis is also called a diplontic life cycle. (wikipedia.org)

The epic battle for the cell is to have the regularly expected circadian cycles found in our environment and "yoke" those signals to its metabolic cycle and to its growth cycle. (jackkruse.com)
The cascade continued until several weeks later, millions of cells were dividing - powering the exponential pattern of growth that eventually formed all of the organs and tissues of your body. (visionlearning.com)
The cell cycle is a series of carefully regulated events, including periods of growth, rest, and cell division. (coursehero.com)
This regulation is necessary to prevent a loss of control of cell growth. (sciencing.com)
Decreased expression of NBPF1 in neuroblastoma cell lines with loss of 1p36 heterozygosity and the marked decrease of anchorage-independent clonal growth of DLD1 colorectal carcinoma cells with induced NBPF1 expression further suggest that NBPF1 functions as tumor suppressor. (biomedcentral.com)

A life cycle is the continuous sequence of changes undergone by an organism from beginning of life till death. (powershow.com)
What surprises many people is that every body cell of an animal - indeed, of any multicellular organism - carries its entire genome. (learner.org)
If it doesn't, daughter cells won't form properly (or at all) and this may have a negative impact on the entire organism. (learner.org)
This is important because male and female sex cells ultimately join to become a fertilized egg, which gives rise to a new organism, or offspring. (learner.org)
The three germ layers and the body plan of the mature organism are established during gastrulation, and the period is characterized by extensive cell movements and intracellular communications [ 21 , 22 ]. (biomedcentral.com)

What evolutionary advantage does asynchronous mitosis bring to Plasmodium spp asexual replication? (iu.edu)

Patterns are ubiquitous in living systems and underlie the dynamic organization of cells, tissues, and embryos. (mpi-cbg.de)

A poorly understood feature of these responses is the delayed onset (days), in contrast to the acute DNA-damage responses that occur in minutes to hours. (nature.com)

Mitosis could be symmetric leading to self-renewal from the neural progenitor pool or asymmetric resulting in one neural progenitor and the post-mitotic neuron or an intermediate progenitor each which migrate from the ventricle. (biotech-angels.com)

Once temperature becomes the dominant method of entrainment used to yoke the circadian rhythms to leptin, some very unique things happen to our biochemistry that normally do not occur in other environments. (jackkruse.com)
To claim that researchers in synthetic biochemistry have no idea how to form even a single cell out of prebiotic materials, let alone the complex interactions of many cells within a seed, is no exaggeration. (evolutionnews.org)

The S. cerevisiae ORC binds to specific DNA sequences throughout the cell cycle but becomes active only when it binds to the replication initiator Cdc6. (nature.com)

The precise regulations of pre-RC protein levels and assembly are effective ways to prevent reassembly of de novo MCM2-7 onto the replicated origins to re-license and re-replicate the genomic DNA in the subsequent phases of the same cell cycle ( Figure 1) . (intechopen.com)
Some cells replicate faster and others slower, and the entire process can be interrupted. (visionlearning.com)

How do body cells reproduce? (learner.org)

Interphase takes most of the time in the cell cycle, comprising more than 95% of the duration of the cell cycle in most eukaryotes. (coursehero.com)

After mitosis, daughter cells can either remain proliferative and re-enter the cell cycle or become terminally postmitotic and migrate out of the VZ ( McConnell, 1995 ). (jneurosci.org)
The fundamental work that shows the preferential inheritance of the older centrosomes by the self-renewing daughter cells in human is supported by strong evidence. (elifesciences.org)
When this happens, it is necessary to pass the entire genome to the resulting two daughter cells in order to ensure that each gets a complete set of chromosomes. (learner.org)
It is essential that daughter cells be exact duplicates of the parent cell. (pressbooks.pub)
If this doesn't happen correctly, incorrect numbers of chromosomes can be partitioned into each of the daughter cells, which would likely cause them to die. (pressbooks.pub)
The aim of this process is to produce double the amount of DNA, providing the basis for the chromosome sets of the daughter cells. (wisdomanswer.com)

The pre-replication complex (pre-RC) assembly or the DNA replication licensing is the first step in DNA replication initiation, characterized by the sequential recruitment of ORCs, Cdc6, Cdt1 and MCMs to the DNA replication origins to form the pre-RC at the end of mitosis ( Bell and Dutta 2002 ).
