Concepts In Cell Biology

Cell biology is a scientific discipline that studies cells – their physiological properties, their structure, the organelles they contain, interactions with their environment, their life cycle, division and death. This is done both on a microscopic and molecular level. Cell biology research encompasses both the great diversity of single-celled organisms like bacteria and protozoa, as well as the many specialized cells in multicellular organisms such as humans. Knowing the components of cells and how cells work is fundamental to all biological sciences. Appreciating the similarities and differences between cell types is particularly important to the fields of cell and molecular biology as well as to biomedical fields such as cancer research and developmental biology. This book covers all the aspects of this subject. It is hoped, the book will be found to be of immense value to the students of this subject. Contents: • Cell Signalling and Gene Transcription • DNA Replication • RNA Extraction • Human Chromosomes • Structural Organization of the Nucleus • Functions of Noncoding DNA • Chemical Environment of Cell • Implications of the RNA World • Enzyme Structure • From Organic Molecules to Protocells
