1, Embryos grow by cell division .

2, But all embryos grow by cell division.

3, They therefore play an important part in cell division.

4, Nobody has to remind me that frequent cell division is not by itself malignancy.

5, She, however, also added chemicals which inhibit normal cell division.

6, The genes for cell division did not evolve to separate different kinds of fish.

7, In cell division the spiral appears, as well as in the DNA molecule in the cell nucleus.

8, They are the first to divide in cell division and form the poles at each end of the cell.

9, Cell division is very risky business , Campisi observes.

10, The DNA of chromatin must replicate before cell division.

11, Dynein also helps force apart chromosomes during cell division.

12, In the secondary maturation cell division the secondary spermatocyte generated spermatid containing 32 nuclei with round, spindle and crescent shapes, which eventually developed into 32 spermatozoon.

13, Root growth is mainly determined by cell division and subsequent elongation in the root apical area. Components regulating cell division in root meristematic cells are largely unknown.

14, Asymmetrical cell division is a process by which a cell gives rise to two different daughter cells through the unequal inheritance of specific molecules.

15, FW 2.2 as a negative regulator of cell division in tomato fruit.

16, Karyokinesis During cell division,(http://sentencedict.com/cell division.html) the process of nuclear division that precedes cytoplasmic division.

17, Its binary cell division characteristic with wall invagination and possible trichome fragmentation resulting from a dead cell, are typical reproductive modes of modern cyanobacteria.

18, Young etiolated leaves may also be accompanied by cell division.

19, The value of graphic material is to attract attention and convey information in a summarised form, e.g. cell division.

20, It arises from a failure of the machinery that controls cell division.

21, It is these cells which will later give rise, by further cell division, to eggs or sperm.

22, These genes are duplicated along with the chromosomes at each cell division and can be passed down from parents to their offspring.

23, Convoluted invaginations of the cell membrane form specialized structures called mesosome which function in the formation of cross-wall during cell division.

24, Wilmut said there were so many failures because it was difficult to ensure that the empty oocyst and the donor cell were at the same stage of the cell division cycle.

25, On rat brain samples, the researchers applied antibodies to identify proteins that may be involved in asymmetric cell division, and they found that polarization exists on the ependymal cells.

26, In nature, clones are derived from a single parental organism or cell by mitotic cell division, asexual reproduction, or parthenogenesis.

27, Approximately four days after fertilization and after several cycles of cell division, these totipotent cells begin to specialize.

28, Chapter 1 gives an overview of the modeling of the cell division cycle.

29, In addition, both monomeric and dimeric CPAP are required for accurate cell division, suggesting that the temporal dynamics of CPAP homodimerization is tightly regulated during the cell cycle.

30, Studied the affection of medical stone on the seed germination and cell division of cucumber.
