It is immensely powerful in biological systems — it adds long-term stability to gene expression states and increases the robustness of gene regulatory networks. The Polycomb group (PcG) and Trithorax group (TrxG) proteins can confer long-term, mitotically heritable memory by sustaining silent and...
DNA replication errors activate O-GlcNAcylation to control the function of the tumor-suppressor p53 at Gap Phase 2 (G2). Finally, in mitosis (M phase), O-GlcNAc controls M phase progression and the organization of the mitotic spindle and midbody. Critical for M phase control is the ...
How long is the period of cell division in an embryo when compared to that of a normal cell?Answer and Explanation: During the cleavage period, when the zygote begins mitosis, the cell division for each cell takes between 12 and 24 hours....
How is the mitotic phase different from meiosis? How is genetic variation produced in meiosis? Cryptorchidism is failure of the testes to descend. Explain why this would cause sterility if not corrected. Cryptorchidism is the failure of the testes to descend. Explain why this would cause s...

(HFD) on rat SCs were not evaluated. However, the absolute testis weight was decreased in both rats with short- and long-term obesity80. Since testis weight in the prepubertal phase is mainly given by the number of SCs, possible damage to SCs and an alteration of their proliferation ...
In this state, molecular entities exhibit a preferred directionality without long-range positional order. Osmotic pressure Pressure caused by a difference in the amounts of solutes (or molecules) between solutions (or fluids) separated by a semipermeable membrane. Second harmonic generation microscopy A...

In addition, the tegument protein VP1/2 has long been implicated in DNA release because a HSV-1 temperature-sensitive mutant of this protein (tsB7) binds to the NPC, but does not release its DNA at the nonpermissive temperature [90]. More recently, it has been shown that proteolytic ...
What is the function of mitosis in the cell? Explain the stages of the cell cycle and discuss the events that occur during each stage. Explain how the chromatin structure of chromosomes changes during the mitotic cell cycle. What occurs in each phase of the cell cycle? Explain. What ar...
