Karyokinesis and cytokinesis are independent but spatially and temporally coordinated processes. While mitosis can occur in the absence of cytokinesis, cytokinesis requires the mitotic apparatus. The end of cleavage coincides with the beginning of zygotic transcription.
The relatively brief M phase consists of nuclear division (karyokinesis) and division of cytoplasm (cytokinesis). It is a relatively short period of the cell cycle. M phase is complex and highly regulated. The sequence of events is divided into phases, corresponding to the completion of one set of activities and the start of the next.
In 1832, he described cell division in simple aquatic plants (French 'conferve') as follows (translated from French to English): "The development of the conferve is as simple as its structure; it takes place by the attachment of new cells to the old, and this attachment always takes place from the end.
3' untranslated region (3'-UTR). Also three-prime untranslated region, 3' non-translated region (3'-NTR), and trailer sequence.. 3'-end. Also three-prime end.. One of two ends of a single linear strand of DNA or RNA, specifically the end at which the chain of nucleotides terminates at the third carbon atom in the furanose ring of deoxyribose or ribose (i.e. the terminus at which the 3' carbon ...

the pelta-axostyle system, made of microtubules; it supports the cell axis and is involved in karyokinesis. The pelta is a microtubular structure that holds the flagellar canal. The costa, a rootlet; it supports flagellar movements and provides an anchoring system for the nucleus and Golgi. The parabasal and sigmoid filaments; Other filaments.
Hayflick describes three phases in the life of normal cultured cells. At the start of his experiment he named the primary culture "phase one". Phase two is defined as the period when cells are proliferating; Hayflick called this the time of "luxuriant growth".
