A selection of problems, written by John Wilson and Tim Hunt, appears in the text at the end of each chapter. New to this edition are problems for the last four chapters on multicellular organisms. The complete solutions to all of these problems can be found in Molecular Biology of the Cell, Sixth Edition: The Problems Book which if you want then comment below will upload. Eucaryotic Gene Activator Proteins Promote the Assembly of RNA Polymerase and the General Transcription Factors at the Startpoint of Transcription Proteins That Bind to the 5′ and 3′ Untranslated Regions of mRNAs Mediate Negative Translational Control

Ca 2+/Calmodulin-dependent Protein Kinases (CaM-Kinases) Mediate Many of the Actions of Ca 2+ in Animal CellsLateral Inhibition and Asymmetric Division Combine to Regulate Genesis of Neurons Throughout the Body

Filament Treadmilling and Dynamic Instability Are Consequences of Nucleotide Hydrolysis by Tubulin and ActinAn Egg Is Highly Specialized for Independent Development, with Large Nutrient Reserves and an Elaborate Coat Three Molecules of ATP and Two Molecules of NADPH Are Consumed for Each CO 2 Molecule That Is Fixed The Light-induced Activation of “Caged” Precursor Molecules Facilitates Studies of Intracellular Dynamics Bcl-2 Family Proteins and IAP Proteins Are the Main Intracellular Regulators of the Cell Death Program

Nucleic Acid Hybridization Reactions Provide a Sensitive Way of Detecting Specific Nucleotide Sequences Notch Signaling Regulates the Fine-Grained Pattern of Differentiated Cell Types in Many Different Tissues Three Classes of Segmentation Genes Refine the Anterior- Posterior Maternal Pattern and Subdivide the Embryo Many Proteins and Lipids Seem to Be Carried Automatically from the Golgi Apparatus to the Cell Surface

Excerpt

Transport Between the Nucleus and Cytosol Can Be Regulated by Controlling Access to the Transport Machinery

Four Familiar Signaling Pathways Combine to Pattern the Wing Disc: Wingless, Hedgehog, Dpp, and Notch All Cells Transcribe Portions of Their Hereditary Information into the Same Intermediary Form (RNA) Amazing and thought-provoking, this text can heartily be recommended to any genuine lover of nature. The main impression one draws from this work will be that of layer upon layer of staggering complexity in the workings of the cell. Saddening to reflect that, probably, in the main it must be studied laboriously by hard-pressed undergraduates seeking to pass their examinations rather than pored over eagerly by contemplators of creation. For one must simply marvel at nature’s inventiveness:By Providing an Inexhaustible Source of Reducing Power, Photosynthetic Bacteria Overcame a Major Evolutionary Obstacle Homeotic Selector Genes Code for DNA-Binding Proteins That Interact with Other Gene Regulatory Proteins The Membrane Potential in Animal Cells Depends Mainly on K + Leak Channels and the K + Gradient Across the Plasma Membrane
