To a large extent, the prophase changes in microtubule organization can be explained by two simple biochemical changes: (a) increased microtubule-nucleating activity of centrosomes and (b) altered dynamic instability properties of the microtubules (Table 44.1; also see Chapter 34). Interphase ...
In simple terms, during a downtrend, with bears having absolute control, a stock usually opens lower compared to the previous day's close, and again closes lower. On the day the hammer pattern is formed, maintaining the downtrend, the stock makes a new low. However, after eventually fin...
all chromosome movement regulator mutants also have defects in meiotic double-strand break repair. They accumulate an excess of DMC1 foci, and meiotic progression becomes arrested at zygotene; eventually, meiocytes undergo apoptosis8,23
The recent availability of reproductive tissue-specific expression profiles for humans and mice allows us to monitor gene co-expression and predict plausible new meiotic genes that are important in human reproduction [6–9,15,16]. However, the analyses have been mainly limited to simple clustering ...
Interpretation of an apparent co-localization to the phragmoplast must be made with caution because, due to simple exclusion of organelles by the palisade of microtubules, a more accessible volume for soluble proteins is created within the phragmoplast [30]. However, we noted a difference in ...
G1 phase is the first growth phase and the first sub-phase of the interphase. During the G1 phase, cell resumes its higher rate of biosynthetic activity, cell synthesizes proteins, cell increases the number of organelles and cell grows in size. G1 phase is followed by S phase. During th...
