aAurora A (AurA) kinase is essential for the assembly of the metaphase bipolar spindle and, thus, it has been difficult to address its function during the last phases of mitosis. 极光 (气氛) 激酶为分裂中期双极纺锤的装配是根本的在最后阶段有丝分裂期间,并且,因而,演讲它的作用是难的。[translate...
Cells in the late stages of mitosis, such as telophase, exhibit endocytosis and fusion (Figure 3a), but we could not obtain cells in telophase because no agents were known to arrest cells at telophase without causing apoptosis.23 Hence, we tested only metaphase mitotic cells with live non- ...
Finally, suppression of chromosome-bound rRNAs by RNA polymerase I inhibition or by using rRNA-binding-deficient Ki-67 mutants impair mitotic chromosome dispersion during prometaphase. Our study thus reveals an important role of rRNAs in preventing chromosome clustering during mitosis....
Is this also a phase of mitosis? What stage of cell cycle division is genetic content replicated? a. Interphase b. Prophase c. Metaphase d. Anaphase e. Telophase Which stage of the cell cycle is not part of the interphase? a) G1 (Gap 1) b) S (synthe...
In metaphase, the sister chromatids move towards the opposite poles of the spindle. View Solution Which is unique to mitosis and does not occur in meiosis ? View Solution During meiosis, crossing over occurs between View Solution The events shown below occur during different phases - ...
Prior to fertilization, mammalian oocytes are arrested at the metaphase stage of the second meiotic cell division. The meiotic block is characteristic of the entire animal kingdom and, although it may happen at various stages of the cell cycle, its role is to prevent entry into the embryonic ...
The basal bodies replicate and the kinetoplast divides before the onset of mitosis. At the beginning of mitosis, the chromatin components of the interphase nucleus decondense, the nucleolus undergoes fragmentation and its material partly disappears. At the stage presumably corresponding to the metaphase...
英语翻译原文:Process of MeiosisUnlike the single-cell division of mitosis,meiosis involves two cellular divisions:meiosis I and meiosis II.Each stage of meiosis runs through the same five stages as discussed in mitosis.During the first round
Identify the phase of mitosis in which the the new nuclear membranes form. A) anaphase B) prophase C) metaphase D) telophase During which of these stages of meiosis do homologous chromosomes form tetrads? In what stage of meiosis does trisomy 21 occur?
The decline in the rate of protein synthesis during mitosis in eukaryotic cells was studied using Chinese hamster ovary cells arrested in metaphase with Co... ES Goldstein,S Penman - 《Journal of Molecular Biology》 被引量: 673发表: 1970年 Cell shape and membrane changes in the eight-cell mo...
