Leyla Kalaycıoğlu, Behiç Serpek, Mehmet Nizamlıoğlu, Nuri Başpınar, Ali Muhtar Tiftik In this work, which was prepared as a textbook, up-to-date information on the field of "Biochemistry" is included, as well as classical information. The chapters of our multi-authored book have been discussed in detail by the authors.
The book is a reference resource that can be used by those who are involved in educational activities related to "Biochemistry". Since "biochemistry" is the basis of many fields of science, it has a feature that people in other fields of science can easily benefit from.

Abdurrahman Aktümsek An effort has been made to prepare a textbook covering the latest developments in zoology for students studying biology and taking zoology courses in different faculties. A large number of figures and pictures are presented for better understanding and reinforcement of the subjects.

Mehmet Topaktaş Genetics is the science that studies heredity and heredity in living things. In the science of genetics, besides the classic subjects such as Mendel's Studies, there are also rapidly changing fields, such as in the field of Molecular Genetics. The main thing in a genetics book is to provide the latest information in rapidly changing fields along with classical subjects. In addition, the author should reflect his own views on the book after synthesizing the acquired knowledge. For these reasons, I wanted this book to include not only the topics that I teach my students during limited class hours, but also all the basic topics that should be in a genetics book. That's what I tried to do while writing this book. For this reason, it took many years to write the book, and as a result, this work emerged. I hope that my book will add new richness to the knowledge of the target audience.
Target audience for this book:
• Scientists working in the field of genetics,
• Research assistants working on a postgraduate thesis in the field of genetics and students working on a postgraduate thesis,
• Students of the Biology, Molecular Biology and Genetics Departments of the Faculties of Science and Letters, the Science and Biology Teaching departments of the Faculties of Agriculture, Medicine, Dentistry, Veterinary Faculties, Education Faculties,
• Biology teachers of high schools and science teachers of primary schools and
• People from all walks of life who are interested in genetics.
The fact that the book reaches its goal will make me forget all my tiredness.

Ayla Öber, Gamze Turgay İzzetoğlu The subjects included in molecular biology, cell biology and histology branches have priority in understanding the lessons taken during biology education. Histology, which is the science of tissue, examines the tissues formed as a result of the coming together of similar cells to undertake a certain function, using many different methods.
In this book; First of all, important ways of working for the subject, a brief reminder about the cell, and the formation, classification and briefly functioning of basic tissues such as epithelial tissue, connective tissue, muscle tissue and nervous tissue that cells are structured are discussed. It also focuses on how the basic tissues come together and the organs they form and the emerging systems; Diseases to be associated with each tissue and system are given for general information purposes.
At the end of the book, there is a glossary of words from the book that are not explained in the topic.

Clarifying the molecular mechanisms of cell division and proliferation and learning the molecular pathways in the cell indicate that more research is needed on molecular structures to be targeted in cancer therapy.
We hope that the book "Cancer Genetics and Molecular Biology" will be a useful resource containing up-to-date information that will benefit scientists who will do research in this field and our students studying in departments such as Medicine, Molecular Biology and Genetics, Biology, Biochemistry, Pharmacy and Veterinary.
In the book, cancer epidemiology, carcinogenesis, molecular targets and signaling pathways in cancer, cancer genetics and cytogenetics, genes responsible for cancer, the relationship between cellular aging and cancer, cell death mechanisms and cancer, characteristics of cancer cells, cancer types, angiogenesis, metastasis, immunity, plasticity, topics such as cancer stem cells, biomarkers, ion channels and cancer relationship and multi-drug resistance in cancer are discussed.

Behiç Serpek The Organic Chemistry book, which was mainly prepared to be useful to students in biology-based faculties such as Medicine, Veterinary Medicine, Dentistry and Pharmacy, consists of two parts, Basic and Organic Chemistry. The first chapter starts with the structure of atoms, which are the smallest building blocks that show all the qualities of an element, and covers chemical bonds, acids and bases, important physicochemical principles, and thermodynamics with analytical methods.
In the second part, the basic principles of organic chemistry, also defined as C-Chemistry, isomer, biologically important organic substance groups and reactions specific to these groups, monomers such as amino acids and monosaccharides in the structure of living things, polymers such as proteins, polysaccharides and nucleic acids are important biochemically. molecular structures have been tried to be given briefly and concisely.
It is thought that the book, which tries to emphasize the biological and biochemical importance of the subjects prepared in color so that the changes in the molecular structures during chemical reactions can be seen more clearly and the shapes can be observed more easily, will contribute to the education in the faculties that provide biology-based education and close the gap on this subject.

Abdurrahman Aktümsek, Gökalp Özmen Güler, Yavuz Selim Çakmak, Gökhan Zengin This book has been prepared for faculty or college students who take the biochemistry course in a short period of time, such as one semester. Although there are many translated and written biochemistry books in our country, what makes this book unique among them is that it has a content and appropriate volume that students can easily understand.
In the writing of the book, one of the most valid methods in learning and teaching, the "general to detailed method" was applied. At the beginning of each topic, a brief summary of that topic is given and then the details of the topic are given.
In order to better understand the information, the written information is associated with examples and analogies and supported by many formulas, pictures and tables.

Abdurrahman Aksoy, Ayhan Filazi, Begüm Yurdakök-Dikmen, Sinan İnce, Yavuz Kürşad Daş Veterinary toxicology is a discipline that is considered within the scope of "single health" and deals with the issue of whether chemical substances that can be found in animal products can harm the health of people in contact with them, as well as poisons that affect animals for their economic pursuit or satisfaction. It is an inevitable fact that events such as climate change, which occur as a result of the damage caused by humans to nature, will affect animals in a significant way. All over the world, animals and humans have to live in a more polluted environment today than in the past, and no one can guarantee a better environment in the future. Most of the toxicological problems are global, but only a few are regional or local, and unfortunately most of these common poisons do not have an antidote. Therefore, facing the new challenges of the 21st century is the most important task of toxicologists. In their subject matter, farm animals are often complicated by the fact that the responses of our lovable animal companions, aquatic and wild animals to poisons are quite broad and vastly different. Likewise, the toxicity of a chemical varies depending on the environment of the animal and many other factors. Thus, in the work, there is information about the poisons that cause poisoning in animals, their sources, their way of entry into the body, their distribution, metabolism, excretion, their effects on animals, diagnostic methods, prevention and treatment approaches, as well as the substances that cause environmental pollution and how to be protected from them.

Ayla ÖBER Zoology course is the most basic course for all biologists. During the undergraduate education, zoology will be used in all the courses to be studied, and the requirements for a better understanding of this course will increase. In the book prepared to meet this need, zoology in general terms; cell and tissue systems and the structuring of tissues are discussed on the basis of embryological development. Under thirteen chapters in total; disciplines in biology, ways of examining biological events, cell and cell science, cell elements, functions of the nucleus, reproduction-reproduction, embryology, organization-histology in living things, organs and systems, diversity of life, ecology and behavior are discussed. Biodiversity is given as an introduction to the information to be obtained in the systematics of invertebrate and vertebrate groups, and ecology and behavior issues form a preliminary information for the following years.
Working with the third edition is for biologists and anyone interested in biology; It will be useful because it provides the opportunity to meet with biology and convey the basic subjects in an understandable language.
