A - Alanine (1 letter) Activation of enzymes through ligand binding: why would this be useful? - The binding of a ligand to an allosteric site of a multimeric enzyme often induces positive cooperativity, that is the binding of one substrate induces a favorable conformation change and increases the enzyme's likelihood to bind to a second substrate. Ala - Alanine (3 letter) Arg - Arginine (3 letter) Asn - Asparagine (3 letter) Asp - Aspartic Acid (3 letter) Barr body and relation to hete...

Growth factors stimulate what? (A) cyclin production. (B) the cell to skip the S and G1 phases of interphase and undergo mitosis directly. (C) Cdk's to synthesize enzymes that digest cyclins. (D) the cell to ignore the checkpoints of the cell cycle. (E) NONE OF THE ABOVE - Answer (A) cyclin production What is a major difference between mitosis and meiosis? (A) Meiosis produces two daughter cells instead of the four daughter cells produced in mitosis. (B) Meiosis produces genetically ide...

Interphase - cell grows, performs its normal functions, and prepares for division; consists of G1, S, and G2 phases G1 phase - the cell grows in size and organelles double in size S phase - DNA replication ("S"= synthesize) G2 phase - cell growth, production of enzymes and other proteins two categories of mitosis - 1. karyokinesis (division of cell nucleus) 2. cytokinesis (division of cytoplasm) prophase - 1. chromatin condenses to form chromosomes; nuclear membrane and nucleol...
