About the Book
Cell and molecular biology is an every dynamic area of life sciences where the core activity of all biological developments are studied in depth. 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. Molecular biology and the discovery of the genetic code had a profound effect on evolutionary biology. One shocking realization was that many sites for mutation—for example, the third position in a codon or a nucleotide in the middle of an intron (a term defined later), are expected to be invisible to natural selection. This led Motoo Kimura to propose the neutral theory of evolution. It was somewhat heretical when first proposed because it deemphasized the role of natural selection, but the theory states that the majority of sequence evolution is purely random, the product of mutation and drift. The book of cell and molecular biology is primarily intended to assist in the accomplishment of exploratory as well as result oriented studies for the students teachers and researchers of life sciences, biotechnology, genetics and plant breeding.
