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...
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...

The differentiation phase begins after the cessation of SC mitotic activity. This phase occurs during puberty, when SCs begin to express AR and the intratubular concentration of T increases, in a LH-dependent manner15. During this process, SCs form the blood-testis barrier (BTB), separate the ...
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...
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....
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 is DNA transmitted to cells? Mitosis and Meiosis The mitotic cycle includes one cell division after a relatively long resting and growth period in between. The meiotic cell cycle includes two cell divisions that result in four daughter cells. ...
