In fact, the more we find out about cells, the more new questions emerge. These brief lists include only a tiny sample of the critical unanswered questions and challenges for the next generation of scientists.

We derive great pleasure from the knowledge that some of our readers will provide future answers. The more than illustrations have been designed to create a parallel narrative, closely interwoven with the text. We have increased their consistency between chapters, particularly in the use of color and of common icons; membrane pumps and channels are a good example. To avoid interruptions to the text, some material has been moved into new, readily accessible panels.

Most of the important protein structures depicted have now been redrawn and consistently colored.

To avoid interruptions to the text, some material has been moved into new, readily accessible panels. Most of the important protein structures depicted have now been redrawn and consistently colored.

These connections allow readers of the book to explore more fully the proteins that lie at the core of cell biology. John Wilson and Tim Hunt have again contributed their distinctive and imaginative problems to help students gain a more active understanding of the text.

The problems emphasize quantitative approaches and encourage critical thinking about published experiments; they are now present at the end of all chapters. The answers to these problems, plus more than additional problems and solutions, all appear in the companion volume that John and Tim have written, Molecular Biology of the Cell, Sixth Edition: The Problems Book. We live in a world that presents us with many complex issues related to cell biology: biodiversity, climate change, food security, environmental degradation, resource depletion, and human disease.

We hope that our textbook will help the reader better understand and possibly contribute to meeting these challenges. Knowledge and understanding bring the power to intervene.

We are indebted to a large number of scientists whose generous help we mention separately in the detailed acknowledgments. Here we must mention some particularly significant contributors. Before starting out on the revision cycle for Molecular Biology of The Cell Sixth edition, we asked a number of scientists who had used the last edition to teach cell biology students to meet with us and suggest improvements.

They gave us useful feedback that has helped inform the new edition. We also benefited from the valuable input of groups of students who read most of the chapters in page proofs. Control of Gene Expression. Analyzing Cells, Molecules, and Systems 9. Visualizing Cells. Membrane Structure Intracellular Compartments and Protein Sorting Intracellular Membrane Traffic Energy Conversion: Mitochondria and Chloroplasts Cell Signaling The Cytoskeleton 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.

References: A concise list of selected references is included at the end of each chapter. These are arranged in alphabetical order under the main chapter section headings. These references sometimes include the original papers in which important discoveries were first reported.

Nomenclature for Genes and Proteins Each species has its own conventions for naming genes; the only common feature is that they are always set in italics. In some species such as humans , gene names are spelt out all in capital letters; in other species such as zebrafish , all in lowercase; in yet others most mouse genes , with the first letter in uppercase and rest in lowercase; or as in Drosophila with different combinations of uppercase and lowercase, according to whether the first mutant allele to be discovered produced a dominant or recessive phenotype.

Conventions for naming protein products are equally varied.
