toplasmic polarization signaling proteins commonly divided into three groups called the Par, Scribbled, and Crumbs complexes, and activation of the small GTPases Rac1 and Cdc42 (Nelson 2009). The extrinsic polarization mechanism, on the other hand, provides spatial orientation cues to the cell from the environment, triggering the asymmetric distribution and activation of the complexes that make up the intrinsic mechanism. In early embryos, primary spatial cues take a variety of forms. ...

It is true that a eukaryotic cell: ○ Is smaller than a prokaryotic cell. ○ Contains structures called organelles. ○ Lacks a well-defined nucleus. ○ Does not contain histones. Eukaryotes are large, have membrane-bound intracellular compartments called organelles, has a well-defined nucleus, and have histones. The function of a histone found in a eukaryote cell focuses on cellular: ○ Division ○ Movement ○ Activities ○ Deoxyribonucleic acid (DNA) folding These proteins b...

Type I hypersensitivity - CORRECT ANSWER (atopic or anaphy-lactic) is an immediate allergic or anaphylactic type of reaction mediated pri-marily by sensitized mast cells How is Type I hypersensitivity initiated? - CORRECT ANSWER initiated when IgE antibodies located on the mast cell membrane are bound by antigen, with subsequent cross-linking of IgE receptors. Mast cell degranulation releases chemicals that mediate the signs and symptoms of anaphylaxis. What is released and caused ...

Structure of Nucleus. 1. Nuclear envelope: double membrane surrounding nucleus, outer membrane continuous with the (R)ER of the cell. 2. Nuclear pores: allow the passage of larger molecules, such as mRNA, out of the nucleus. 3. Nucleoplasm: granular, jelly-like material making up the bulk of the nucleus. 4. Chromosomes: protein-bound, linear DNA. 5. Nucleolus: small spherical region(s) in nucleoplasm. Manufactures ribosomal RNA and assembles ribosomes. Function of Nucleus. 1. Controls...
